Moisture Calculator

Instructions

Enter the air temperature (C) and wet bulb or dew point temperature or RH. All other values, except wet bulb, will be recalculated when you click or tab away from the entry box. Click on the "Lock DP" box to enter a new temperature at the same dew point. This allows calculation of the RH that the air will acquire at a different temperature.

Note: This calculator makes approximations that limit its use to the natural climate near sea level.
