Water Vapour / Dew Point
Water vapour and dew point
Use either relative humidity or dew point to estimate atmospheric water-vapour conditions.
Dew point
Saturation vapour pressure
Actual vapour pressure
Absolute humidity
These values are estimates based on the Magnus approximation over liquid water. The input range is −45 to 60°C for temperature and dew point, and 0.1 to 100% for relative humidity. Dew point must not exceed air temperature. Use dedicated measurements and applicable standards for precision meteorological or industrial work.
