DewPtCm

Dew point in deg. Celsius

Free · Designed for iPad

Compute dew point from old fashioned wet and dry bulb thermometer readings. No internet access needed. This app computes the dew point temperature and relative humidity from a wet bulb temperature, dry bulb temperature and barometric pressure. If a barometer is not available a guess of 760 mm of mercury will usually give a near enough result. Temperatures are in degrees Celsius and pressures in mm of mercury. Uses a computation method suggested by the National Weather Service of the National Oceanic and Atmospheric Administration, USA.
