WebFeb 19, 2024 · Relative humidity is the ratio of the amount of water vapor in the air to its saturation point. Often relative humidity is defined as the amount of water vapor in the air to "how much it can hold" at a given temperature. The notion of a holding capacity is dispelled when one considers what saturation really means. WebHere are some formulas you can use: Equation 1: RH = E/Es × 100. In this equation, RH means relative humidity, E is the amount of water vapor, and Es refers to the amount of water content that would be in the air with an equal temperature and pressure level.
