Humidity is the amount of water vapor in the air.

Humidity Ratio (X)= mw / ma   

where

 

x = humidity ratio (kgwater/kgair, lbwater/lbdry_air)

mw = mass of water vapor (kg, lb)

 

ma = mass of dry air (kg, lb)

Humidity Ratio by Vapor Partial Pressure

Humidity ratio can also be expressed with the partial pressure of water vapor:

x =0.62198 pw / (pa - pw)         (2)

where

pw = partial pressure of water vapor in moist air (Pa, psi)

pa = atmospheric pressure of moist air (Pa, psi)
