Relative humidity / dew point online calculation tool

Relative humidity / dew point online calculator (using dry bulb, wet bulb temperature) software.

Relative humidity calculation formula:

\(Ψ = \frac {Ρ_u }{Ρ _{u,max}} \times 100%= \frac {e}{E} \times 100%= \frac {s}{S} \times 100%\ )

In the formula:

Ρw – absolute humidity in grams per cubic meter

Ρw,max – maximum humidity in grams per cubic meter

e – vapor pressure in Pascal

E – saturated vapor pressure in Pascal

s – specific humidity, in grams per kilogram

S – highest specific humidity, in grams per kilogram
