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
ratio of the actual vapour pressure of water in the air to that in air saturated with water vapour; it is often expressed as a percentage. See humidity.
