Humidity is the amount of water vapor in the air. Too much or too little humidity can be dangerous. For example, high humidity combined with hot temperatures is a combination that can be a health risk, especially for the very young and the very old. Humidity plays an important role in our daily weather.
Basic Calculations. Introduction. Relative humidity (RH) is the actual amount of water vapor in the air as a percentage of the maximum amount of water vapor which the air could hold at a given temperature. When air is warmed, its ability to hold water vapor is increased, and when cooled, it can hold less water vapor.
