Calculator for atmospheric moisture
Enter 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
Click on the "Lock DP" box to enter a new temperature at the same dewpoint.
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.
