Formula





Where,
e = Actual vapor pressure,
e_s = Saturated vapor pressure,
p_sta = Station pressure,
w = Actual Mixing ratio,
w_s = Saturated Mixing ratio,
rh = Relative humidity.

Mixing ratio is explained as the ratio of the mass of water vapor and the mass of dry air. Actual and saturated ratio is very important in determining the weather report.
