Select English or SI Units Select Input Criteria - the calculator will solve for the other value. Air Flow Rate​ Air Change Rate Enter the room height Select how to enter the room area: Enter the area directly​ Enter the length and width of the room Click the Calculate button The results will be displayed in the results window Jump to an Example Air Change Rate RELATED CALCULATORS: Coil Selection Calculator Condensate Generated Duct Size Calculator Psychrometric Calculations Air Change Rate Calculation Example Methodology, Equations, and Example: ​ Air change rate, also known as air changes per hour (ACH), measures the number of times the air within a space is completely replaced with fresh air in one hour. It is commonly used to assess and quantify the ventilation efficiency of a room or building. The air change rate is calculated by dividing the total volume of air supplied or extracted from the space by the volume of the space itself. The result is expressed as the number of air changes per hour. ​ ​ Q = ACH x 1hr/60 min x Room Volume ​ Where: Q - Air Flow Rate [ CFM ( l/s )] ACH - Air Changes per Hour Room Volume - L x W x H ​ Example : What volume of Air needs to be supplied to a 12'-0" x 12'-0" room that is 14'-0" high to achieve 3 air changes per hour? ​ Q = (3 Air Changes/hr) x (1hr / 60 mins) x (12'-0" x 12'-0" x 14'-0") = 100.80 CFM (Cubic Feet per Minute) ​ The air change rate is important because it directly impacts indoor air quality and occupant comfort. Here are a few reasons why ACH is used: ​ Ventilation and air quality: Higher ACH values indicate better ventilation and improved air quality. Increasing the rate of air changes helps remove indoor toxins, including odors, volatile organic compounds (VOCs), carbon dioxide, odors, and airborne contaminants. Fresh air is introduced while stale air is expelled, reducing the risk of respiratory issues and promoting a healthier environment. Temperature and humidity control: Proper ventilation through sufficient air changes helps maintain comfortable temperature and humidity levels. It prevents the buildup of excess heat or moisture, which can lead to discomfort, mold growth, and other issues. Controlling airborne pathogens: In settings such as hospitals, laboratories, and cleanrooms, controlling airborne pathogens is crucial. Higher air change rates help dilute and remove infectious particles, reducing the risk of spreading diseases. Compliance with building codes and standards: Many building codes and standards specify minimum air change rates for different types of spaces. These guidelines ensure that occupants have an acceptable air quality and comfort level. ACH values are used to verify compliance during building design, construction, and operation. ​ It's important to note that the optimal air change rate depends on various factors, including the size and function of the space, occupancy levels, and specific requirements or regulations. Engineering professionals and building designers consider these factors in determining the appropriate ACH for a particular environment.

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. What is absolute zero in Kelvin, K? ​ K = 0°R x 5/9 = 0 K Convert to Fahrenheit Convert to Celsius Convert to Rankine Covert to Kelvin
