WebOct 22, 2024 · Relative Humidity (RH) is a measure of how saturated the air is at its current temperature. Since warm air can “hold” more water vapor than cool air, the RH of warmer air will be lower than cool air, even with the same amount of water vapor. When the relative humidity is high, the air feels damp and sticky. 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. Equation 2: RH = 100 × E × ( (243.04 × 17.625 (Td−T) ) / ( (17.625 + T) × (17. ...
