It converts temperatures between Fahrenheit, Celsius, Rankine, and Kelvin scales quickly and accurately. These conversions allow individuals to switch between the most commonly used temperature units, effectively communicating and working with temperature data in various contexts. ​ The calculator is helpful for students studying science, engineering, or any subject involving temperature measurements who often convert temperatures between different units. Scientists and Researchers in various scientific fields, such as physics, chemistry, meteorology, and engineering, may frequently need to perform temperature conversions. Those working in industries where temperature is critical, such as manufacturing or HVAC, may use temperature unit converters to make precise conversions for their applications. ​ ​ The Fahrenheit temperature scale is used primarily in the United States and a few other countries for various purposes. It is one of the four main temperature scales commonly used, the others being Celsius, Fahrenheit, and Kelvin. Fahrenheit is the primary temperature scale used in the United States for everyday weather reports, indoor and outdoor temperature measurements, and personal reference. In countries that predominantly use the Fahrenheit scale, people are familiar with it for day-to-day temperature comparisons. Fahrenheit is often used in HVAC systems in the United States for temperature control and settings in homes, buildings, and vehicles.Despite its prevalence in the United States, the Fahrenheit scale is less commonly used in most other parts of the world, where the Celsius scale is the standard for scientific and daily temperature measurements. ​ Formula to Convert Celsius to Fahrenheit: °F = (°C x 9/5) + 32 Formula to Convert Rankine to Fahrenheit: °F = °R - 459.67 Formula to Convert Kelvin to Farenheit: °F = (K − 273.15) × 9/5 + 32 ​ ​ Example : Water freezes at 0°C. What is the freezing point of water in °F? ​ °F = (0°C x 9/5) + 32°F = 32°F ​ The Celsius temperature scale, also known as the centigrade scale, is used widely for various purposes and in many countries around the world. It is one of the most common temperature scales and is based on the freezing and boiling points of water under standard atmospheric conditions. In the Celsius scale, the freezing point of water is defined as 0 degrees Celsius (°C), and the boiling point of water is defined as 100 degrees Celsius (°C). Celsius is commonly used in daily life to express air temperatures, weather forecasts, and indoor temperatures. It is the standard temperature scale used in weather reports and daily temperature measurements in many countries. Celsius is frequently used in scientific research, particularly in fields like biology, chemistry, and medicine. It provides a practical and straightforward scale for most laboratory experiments and temperature-related studies. Celsius is part of the International System of Units (SI), making it a global standard for temperature measurement in scientific publications and international collaborations. ​ Formula to Convert Fahrenheit to Celsius: °C = (°F - 32) x 5/9 Formula to Convert Kelvin to Celsius: °C = K - 273.15 Formula to Convert Rankine to Celsius: °C = (°R − 491.67) × 5/9 ​ Example : Water boils at 212°F. What is the boiling point of water in °C ​ °C = (212°F - 32) x 5/9 = 100°C ​ The Rankine temperature scale is primarily used in engineering applications, especially in the United States. The Rankine scale is an absolute temperature scale, similar to Kelvin, with 0 Rankine representing absolute zero. However, while Kelvin is used in scientific and international contexts, the Rankine scale is more commonly used in the U.S. engineering community, especially in fields such as thermodynamics, fluid mechanics, and heat transfer. One significant advantage of using the Rankine scale in engineering applications is that it aligns with the Fahrenheit scale, which is commonly used in the U.S. This makes it easier for engineers and technicians to work with temperature data without needing to convert between Celsius and Fahrenheit units. ​ Formula to Convert Fahrenheit to Rankine: °R = °F + 459.67 Formula to Convert Celsius to Rankine: °R = °C × 9/5 + 491.67 Formula to Convert Kelvin to Rankine: °R = K x 9/5 ​ ​ Example: The temperature of the surface of this sun is 5,772 K. What is the equivalent temperature of the surface of the sun in Rankine, °R? ​ °R = 5,772 K x 9/5 = 10,389.6°R ​ ​ ​ The Kelvin temperature scale is used primarily in scientific and international contexts. The Kelvin scale is an absolute temperature scale, meaning 0 Kelvin represents absolute zero, the lowest possible temperature where all molecular motion ceases. It is based on the Kelvin temperature unit, denoted by "K." Kelvin is the preferred temperature scale in most scientific disciplines, including physics, chemistry, astronomy, and atmospheric sciences. Its use is particularly prevalent in research involving extreme temperatures, cryogenics, and studies of fundamental physical phenomena. The Kelvin scale is part of the International System of Units (SI), which is the standard system of measurement used internationally. As the SI unit for temperature, it is employed in scientific publications, academic research, and international collaborations. While the Kelvin scale is not as commonly used in engineering as Celsius or Fahrenheit, it still finds applications in certain engineering fields, such as materials science, aerospace engineering, and thermal analysis. In laboratories and controlled experimental environments, Kelvin is often used when precise and accurate temperature measurements are required. In space missions and interplanetary explorations, Kelvin is used due to its absolute nature and consistency across different scientific disciplines. Overall, ​ ​ Formula to Convert Celsius to Kelvin: K = °C + 273.15 Formula to Convert Fahrenheit to Kelvin: K = (°F -32) x 5/9 + 273.15 Formula to Convert Rankine to Kelvin: K = °R x 5/9 ​ Example: Absolute 0 is represented as 0°R.

The results will be displayed at the bottom of the table. Methodology, Equations, and Examples: ​ Engineering economics is a specialized field of economics that strategically applies economic principles to the decision-making process within engineering projects. It encompasses a comprehensive analysis of the costs and benefits of different alternatives, with the ultimate aim of evaluating their financial viability. The primary objective is to identify the most economically efficient solution that maximizes benefits while minimizing costs. One of the key pillars of engineering economics is recognizing and considering the time value of money. This concept acknowledges that the worth of money fluctuates over time due to factors such as inflation and the potential for interest or investment returns. Consequently, a dollar received or spent in the future holds a different value than one received or spent today. Engineering economists employ various tools and formulas to precisely assess the financial impact of time, including the future value formula, present value formula, compounding periods, present value (PV), future value (FV), present value calculator, and future value calculator. ​ The future value formula is employed to determine the projected value of an investment or cash flow at a specific time in the future, accounting for compounding periods. This formula considers the initial investment or present value (PV), the interest rate, and the number of compounding periods to calculate the future value (FV) of the investment. By utilizing the future value formula, engineers can estimate the potential growth of an investment over time. ​ Conversely, the present value formula calculates the current worth of an expected future cash flow or investment. It considers the future value (FV), the interest rate, and the number of compounding periods to compute the present value (PV). This formula is crucial in determining the current value of future benefits or costs associated with engineering projects. ​ Engineers frequently employ present and future value calculators to simplify these calculations. These tools enable precise assessments of the worth today (present value) or the projected value in the future (future value) of cash flows or investments. Engineers can make informed decisions based on accurate financial evaluations using such calculators. Engineering economics combines economic principles with engineering project decision-making. It involves assessing costs and benefits, considering the time value of money, and utilizing formulas such as the future value formula and present value formula. Furthermore, using compounding periods, present value calculators, and future value calculators enables engineers to evaluate the financial viability of alternatives and determine the optimal solution for their projects. ​ The terms used in this calculator are defined as follows: ​ A - Annual Worth or Equivalent Annual Cost F - Future Value G - Gradient (or Gradient Series) i - Interest Rate (or Discount Rate) n - Number of Time Periods P - Present Value ​ Here are the formulas used in the Engineering Economics Calculator, along with examples for each: ​ Compound Amount (F/P, i, n): The compound amount formula (F/P) calculates the future value of a present sum of money after compounding at a given interest rate for a specific number of periods. ​ To find F, given P: (F/P, i, n) F = P(1+i)^n ​ Example: If you invest $5,000 in a savings account with an annual interest rate of 5%, how much will you have after 10 years? ​ F/P = $5,000 x (1 + 0.05)^10 = $8,144.47 ​ ​ Present Worth (P/F, i, n): The present worth formula (P/F) computes the current value of a future sum of money that will be received or paid at a future date, discounted back to the present at a given interest rate. ​ To find P, given F: (P/F, i, n) P = F(1+i)^(-n) ​ Example: If you expect to receive $10,000 3 years from now, and the discount rate is 4% , what is the present value of that amount? ​ P/F = $10,000 x (1 + 0.04)^-3 = $8,889.96 ​ ​ Series Compound Amount (F/A, i, n): The series compound amount (F/A) formula determines the future value of equal cash flows invested or received at regular intervals over a specific period at a given interest rate. ​ To find F, given A: (F/A, i, n) F = A [ ( (1+i)^n - 1) / i ] ​ Example: If you invest $500 at the end of each year for the next 8 years with an interest rate of 8% , how much will you have at the end of 8 years? ​ F/A = $500 x [((1 + 0.08)^8 - 1) / 0.08 ] = $5,318.31 ​ ​ Series Present Worth (P/A, i, n): ​ The series present worth formula (P/A) calculates the equivalent present value of equal cash flows received or paid at regular intervals over a specific period at a given interest rate. ​ To find P, given A: (P/A, i, n) P = A [ ((1+i)^n - 1) / (i (1+i)^n ) ] ​ Example: You will receive $1,000 at the end of each year for the next 5 years, and the interest rate is 7%. What is the present value of this cash flow series? ​ P/A = $1,000 x [ (( (1 + 0.07)^5-1) / (0.07 (1 + 0.07)^5)] = $4,100.20 ​ ​ Sinking Fund (A/F,i,n): ​ The sinking fund factor (A/F) calculates the regular payments (or deposits) needed to accumulate a specified amount of money in a fund at a future time, with a given interest rate. It is commonly used to plan for the replacement or upgrade of an asset. ​ To find A, given F: (A/F, i, n) A = F x i / [ (1+i)^n - 1 ] ​ Example: You want to accumulate $10,000 in a sinking fund over 5 years with an annual interest rate of 6%. Using the sinking fund formula, you can calculate the regular payments required: A/F = $10,000 x 0.06 / [ (1 + 0.06)^5 - 1] = $1,773.96 ​ ​ Capital Recovery (A/P,i,n): The capital recovery factor (A/P) calculates the equal periodic payments required to recover the initial investment and cover the interest costs over a specific period. ​ To find A, given P: (A/P, i, n) A = P [ i (1+i)^n / ((1+i)^n - 1) ] ​ Example: You need to recover an initial investment of $50,000 over 10 years with an annual interest rate of 8%. Using the capital recovery formula, you can calculate the equal periodic payments required: A/P = $50,000 x [0.08 (1+0.08)^10 / ((1+0.08)^10 - 1) ] = $7,451.47 ​ ​ Compound Gradient (F/G): The compound gradient factor (F/G) calculates the future value of a series of increasing or decreasing cash flows that compound at a given interest rate. ​ To Find F, given G: (F/G, i, n) F = G x [ (1+i)^n - 1 - ni ] / i^2 ​ Example: Suppose you have a series of cash flows that increase by $2,000 every year for 8 years, and the interest rate is 5%. Using the compound gradient formula, you can calculate the future value of the cash flows: F/G = $2,000 x [ (1 + 0.05)^8 - 1 - 8 x 0.05 ] / 0.05^2 = $61,964.36 ​ ​ Discount Gradient (P/G): The discount gradient factor (P/G) is used in engineering economics to calculate the present worth of a series of cash flows that change over time. It considers both the time value of money and the gradient, which represents the rate of change of the cash flows. ​ To find P, given G: (P/G, i, n) P = G x [ ((1+i)^n - in - 1) / ((i^2) (1+i)^n ) ] ​ Example: Suppose you have a series of cash flows that increase by $2,000 every year for 8 years, and the interest rate is 5%. Using the compound gradient formula, you can calculate the present value of the cash flows: ​ P/G = $2,000 x [ (1+.05)^8 - 0.05 x 8 -1) / (( 0.05^2 x (1+0.05)^8) ] = $41,939.91 ​ ​ Arithmetic Gradient Uniform Series (A/G): ​ The Discount Gradient (A/G) formula in engineering economics is used to calculate the present worth or future worth of a series of equal annual cash flows that change by a constant percentage or gradient over time. ​ To find A, given G: (A/G, i, n) A = G x [ ((1+i)^n - in -1) / (i (1+i)^n - i) ] ​ Example: Suppose you are considering a project that will generate an increasing annual cash flow with a constant gradient of $2,000 per year for a duration of 8 years.

Reheat Sizer Related Calculators: kW, HP, Btu/h, Ton, lbf/h Converter Coil Selection Calculator Psychrometric Chart Calculator Air Mixing Calculator Methodology and Equations: ​ In the context of air conditioning, "reheat" refers to a process that involves heating the air after the air conditioning system has cooled it. The purpose of reheating is to control the temperature and humidity levels in a conditioned space more precisely. In the reheat process, after the air has been cooled, it passes through a reheat coil, where it is reheated to a desired temperature and humidity level. The reheat coil is typically equipped with electric heaters or hot water coils. By adding heat back into the air, the system can achieve a more comfortable humidity level while maintaining the desired temperature. ​ Reheat is particularly useful in humid climates or situations where precise control over humidity levels is required, such as in laboratories, data centers, or specific industrial processes. ​ Heating Coil Capacity = 1.0882 x Q x (T Entering - T Leaving ) ​ where: Q = Aiflow, CFM [l/s] T Entering = Entering Coil Temperature, oF [oC] T Leaving = Leaving Coil Temperature, oF [oC] ​ ​ Example: Calculate the necessary reheating coil capacity for a 7.5-ton (3,000 CFM). The room heating set point is 70oF, and the cooling coil leaving air temperature is 52oF. ​ To reiterate the note in the instructions, "for Reheat Coil Sizing Calculations, the Leaving Coil Temperature is customarily set to the room heating setpoint, and the Entering Coil Temperature is customarily set to the cooling coil leaving air temperature." ​ Reheat coil capacity = 1.0882 x 3,000 CFM x (52oF - 70oF) = -58,762.80 BTU/h (where the negative value denotes heating) ​ This can be converted to kilowatts using the formula: 1kW = 3,412.14163 BTU/h ​ = -58,762.80 BTU/h x 1kW / 3,412.14163 BTU/h = -17.22 kW (where the negative value denotes heating) ​ ​ ​ Jump to an Example Reheat Coil Example

U-Facotrs & SHGC Values RELATED CALCULATORS: Energy Form - Commercial Energy Form - Residential SH-# Window Size Converter Duct Size Calculator Jump to Examples Methodology: ​ NFRC U-Factor and SHGC values are critical when performing Cooling Load Calculations and Energy Code Compliance Calculations. Clients can often provide these values if the windows are new with their sticker still attached. As a side note, any window, door, or Skylight with an NFRC rating can be found using the NFRC's searchable database. In the event that the windows are existing or no longer have an NFRC label affixed, the International Energy Conservation Code (IECC) and Florida Energy Conservation Code (FECC) provide default values U-Factor, SHGC values, and VT values. The v alues below are taken directly from the 2020 Florida Energy Conservation Code, Table C303.1.3(1) & (2) , and the 2021 International Energy Conservation Code C303.1.3 (1) & (2) and show SHGC, U-Factor, and VT values for windows and doors: TABLE C303.1.3(1) DEFAULT GLAZED FENESTRATION U-FACTORS TABLE C303.1.3(2) DEFAULT OPAQUE DOOR U-FACTORS TABLE C303.1.3(3) DEFAULT WINDOW, GLASS DOOR AND SKYLIGHT SHGC AND VT Example 1: You are performing a load calculation for an existing building. You do a site visit and see that the existing windows have metal frames and the single-pane glass has no tinting. What values should you use for the U-Factor, SHGC value, and VT value of the windows? ​ Find the U-Factor From Table C303.1.3(1) by looking up Metal Frame / Single Pane windows: U-Factor = 1.2 Find the SHGC and VT From Table C303.1.3(3) by looking up SINGLE GLAZED-Clear windows: SHGC = 0.8, VT = 0.6 ​ Example 2: You are performing a load calculation for an existing building. You do a site visit and see that the existing doors are uninsulated and metal. What value should you use for the U-Factor? ​ Find the U-Factor From Table C303.1.3(2) by looking up Uninsulated Metal: U-Factor = 1.2 ​ Example 3 : Use Adicot's International Energy Conservation CodeWindow U-Factors & SHGC Default Values Calculator to solve the examples above: IECC FECC U-Factor and SHGC Default Examples

Mixed Air Air Mixing Example and Methodology Methodology, Equations and Examples: ​ In HVAC, air mixing involves blending different air streams to achieve desired temperature, humidity, and air quality. It combines supply, return, and outdoor air to create a uniform mixture. Air mixing methods include mixing boxes, diffusers, grilles, and utilizing the Venturi effect. Benefits include improved comfort, enhanced indoor air quality, and energy efficiency. It ensures uniform conditions, dilutes pollutants, and reduces energy consumption. ​ This calculator allows for calculating the mixed air temperature of a third air source. An example of a third air stream is a Bypass air duct that goes from the supply air plenum back to the return air plenum. Trane has an excellent Engineers Newsletter describing Dehumidify with Constant-Volume Systems . The article discusses the Mixed-Air Bypass Method of dehumidification: ​ "Simple and inexpensive, this option blends cold, dry air leaving the cooling coil with warm, moist, mixed air (return air and outdoor air) to achieve the proper supply-air temperature." ​ The equation to calculate the Mixed air of 3 air streams is: ​ TMA = T 1 x Q 1 + T 2 x Q 2 + T 3 x Q 3 Q 1 + Q 2 + Q 3 ​ where: T MA = The dry bulb or wet bulb Mixed Air Temperature, oF [oC] T # = The dry bulb or wet bulb temperature of each airstream, oF [oC] Q # = The flow rate of each airstream, CFM [l/s] ​ ​ Example : Suppose you want to calculate the mixed air temperature of three air streams: Outdoor Air: 150 CFM @ 91oF Dry Bulb / 77oF Wet Bulb Return Air: 1550 CFM @ 75oF Dry Bulb / 62.3oF Wet Bulb Bypass Air: 300 CFM @ 55oF Dry Bulb / 54.5oF Wet Bulb ​ Calculate the Dry Bulb Mixed Air Temperature: ​ TMA, DB = 91oF x 150 CFM + 75oF x 1550 CMF + 55oF x 300 CFM = 73.20oF Dry Bulb 150 CFM + 1550 CMF + 300 CFM ​ Calculate the Wet Bulb Mixed Air Temperature: ​ TMA, WB = 77oF x 150 CFM + 62.3oF x 1550 CMF + 54.5oF x 300 CFM = 62.23oF Wet Bulb 150 CFM + 1550 CMF + 300 CFM
