How do you Calculate Absolute Humidity?
To calculate absolute humidity you only need a couple of variables. The formula for solving absolute humidity is:
Where:
- AH = Absolute Humidity
- AVP = Actual Vapor Pressure (in hPa)
- C = Temperature in Celsius
Understanding Your Results
Your result from this calculator is a single value, the absolute humidity of your specific scenario. It is the total amount of water in the air based on your entries. It is by default displayed as pounds per cubic feet but can be changed into other units of measurement as well.
How to Use the Absolute Humidity Tool
Calculating the absolute humidity of a certain environment is very easy to do with this tool. The steps required to use this tool and get your answer include:
- Enter the relative humidity percent into the first field. Do not enter the percent symbol simply enter the numerical value only.
- Enter the temperature of the air of your scenario. Change the unit of temperature from Fahrenheit if needed.
- Hit calculate and get your absolute humidity value instantly!
Example Calculation
Let's say where you are it is currently 50 degrees Fahrenheit and the relative humidity is at 40%. To find the absolute humidity you can enter 40 into the first field and then enter 50 into the second one. We can then hit calculate and get an answer of .002345 pounds per cubic feet.
