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

(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.
