Air - Absolute Humidity
Absolute humidity is the actual mass of water vapor present in the air water vapor mixture. It can be expressed in SI units (kg/m³, g/m³) or imperial units (lbs/ft³, gr/ft³).

Absolute humidity is the actual mass of water vapor present in an air-water vapor mixture.
Unit Systems
SI Units:
- kg/m³ (kilograms of water vapor per cubic meter)
- g/m³ (grams of water vapor per cubic meter)
Imperial Units:
- lbs/ft³ (pounds of water vapor per cubic foot)
- gr/ft³ (grains of water vapor per cubic foot)
Formula
Absolute Humidity is calculated as the mass of water vapor divided by the volume of the air-water vapor mixture:
$$AH = \frac{m_{H_2O}}{V}$$
Where:
- AH = Absolute Humidity
- m_H₂O = Mass of water vapor
- V = Volume of air-water vapor mixture
