Dew Point Formula
The dew point is calculated using the Magnus formula:
γ = ln(RH/100) + (b·T)/(c+T)
Td = (c·γ)/(b-γ)
Where T is temperature, RH is relative humidity, b = 17.67, and c = 243.5°C.
What is Dew Point?
The dew point is the temperature to which air must be cooled to become saturated with water vapor. It indicates how much moisture is in the air.
