Temperature can only be indirectly measured through certain characteristics of the object that change with temperature. The scale used to measure the numerical value of the temperature of the object is called a temperature scale. Humidity is a physical quantity representing the dryness of the atmosphere. At a certain temperature, the less water vapor contained in a certain volume of air, the drier the air. The more water vapor, the more humid the air. The degree of dryness and humidity of the air is called "humidity". In this sense, physical quantities such as absolute humidity, relative humidity, comparative humidity, mixing ratio, saturation difference, and dew point are commonly used to represent it.
