# Absolute Humidity

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Absolute humidity, abbreviated as AH, is the mass of water vapor divided by the mass of dry air in a certain volume of air at a specific temperature.

## Absolute Humidity formula

 $$\large{ AH = \frac{ m_v }{ V } }$$

### Where:

$$\large{ AH }$$ = absolute humidity

$$\large{ m_v }$$ = mass of water vapor

$$\large{ V }$$ = volume of air
