Humidity is the proportion of water vapour in the air. The relative humidity provides information on the saturation of the air with water vapour in the form of a percentage – always as a function of the temperature. That means: if the relative humidity is 100%, the air is completely saturated and if it is 50%, it is half-saturated with water vapour. You can measure the relative humidity using a hygrometer.
