Relative humidity: the actual water vapor density in air and the percentage of 

saturated water vapor density at the same temperature are called the “relative 

humidity” of air.
The degree of dryness and humidity of the air is related to the degree of saturation of 

water vapor contained in the air, but it is not directly related to the absolute amount of 

water vapor contained in the air.
