relative humidity

n.
The ratio of the amount of water vapor in the air at a specific temperature to the maximum amount that the air could hold at that temperature, expressed as a percentage.

relative humidity

n
(General Physics) the mass of water vapour present in the air expressed as a percentage of the mass that would be present in an equal volume of saturated air at the same temperature. Compare absolute humidity

rel′ative humid′ity


n.
the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature.

rel·a·tive humidity

(rĕl′ə-tĭv)
The ratio of the actual amount of water vapor present in the air at a given temperature to the maximum amount that the air could hold at that temperature. Relative humidity is expressed as a percentage. Compare absolute humidity.

relative humidity

A percentage scale to measure the level of humidity in the atmosphere: from 0% which indicates the air is absolutely dry to 100% which indicates the air is saturated.
