Webhumidity gives the ratio of how much moisture the air is holding to how much moisture it could hold at a given temperature. This can be expressed in terms of vapor pressure and saturation vapor pressure: RH = 100% x (E/Es) where, according to an approximation of the Clausius-Clapeyron WebRelative humidity is also approximately the ratio of the actual to the saturation vapor pressure. RH = (Actual Vapor Pressure) / (Saturation Vapor Pressure) X 100% Where actual vapor pressure is a measurement of the amount of water vapor in a volume of air and increases as the amount of water vapor increases.
