How do you calculate the relative humidity

WebHow do you calculate relative humidity from mixing ratio? Relative humidity is just e/es, the ratio of the vapor pressure to saturation vapor pressure or or w/ws, the ratio of mass mixing ratios of water vapor at actual and saturation values. If you have specific humidity, which is the mass mixing ratio of water vapor in air, defined as: qmvmv ... WebHow do you calculate relative humidity from temperature? The percentage is found by multiplying the ratio by 100%. The RH is NOT the dewpoint divided by the temperature. For example, if the temperature was 60 F and the dewpoint was 30 F, you would not simply take (30/60)*100% = 50% RH.
