Air - Absolute Humidity

Absolute humidity is the actual mass of water vapor present in the air water vapor mixture.

Humidity is the quantity of water vapor present in air. It can be expressed as absolute, specific or a relative values.

Absolute humidity is the actual mass of water vapor - mh20 - present in the air water vapor mixture.

  • In SI-units the absolute humidity may be expressed in kilograms of water vapor (kg/m3, g/m3)
  • In imperial units the absolute humidity may be expressed in lbs of water vapor (lbs/ft3, gr/ft3)
