💧 Dew Point Calculator

Calculate the dew point temperature from air temperature and relative humidity using the Magnus formula.

How to Calculate Dew Point

The dew point is calculated using the Magnus formula: Td = (b × α) / (a - α), where α = (a × T) / (b + T) + ln(RH/100), with a = 17.27 and b = 237.7°C. The dew point indicates the temperature at which air becomes saturated and dew forms. A dew point above 65°F generally feels uncomfortable.
