Air - Absolute Humidity
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)
