## absolute humidity

[′ab·sə‚lüt hyü′mid·ə·dē]
(physics)
The ratio of the mass of water vapor in a sample of air to the volume of the sample.

## absolute humidity

The mass of water vapor per unit volume of air.

## absolute humidity

The mass of water vapor present per unit volume of space (i.e., the density of water vapor, usually expressed in gm/m3). It is the actual amount of water, by weight, in water vapor in a given volume of space. Also known as vapor concentration.
