DewPtF

This app computes the dew point temperature and relative humidity from an input wet bulb temperature, dry bulb temperature and barometric pressure. If a barometer is not available a guess of 29.8 inches of mercury will usually give near enough results. Temperatures are in degrees Fahrenheit and barometric pressure is in inches of mercury. It uses a computation method suggested by the National Weather Service of the National Oceanic and Atmospheric Administration, USA.
