Saturated / Actual Water Vapor Pressure Calculator

Calculate the water vapor pressure from the values of temperature or dewpoint. Relative humidity can also be calculated by knowing these two values.

Formula:


e = 6.11 * 10Sd
es = 6.11*10S
rh = (e * 100 ) / es
Sd = ( 7.5 * Td ) / ( 237.7 + Td  )
S = ( 7.5 * T ) / ( 237.7 + T )
Where, e = Actual Vapor pressure, es = Saturated Vapor pressure, rh = Relative humidity, Td = Dewpoint Temperature in celcius, T = Temperature in celcius.

Actually, saturated / actual water vapor pressure calculator determines the rate of evaporation of liquid in the weather.
