If you use this app, you can very easily calculate humidity, dew point temperature, etc.
The app supports 6 items, "dry bulb temperature", "wet bulb temperature", "dew point temperature", "relative humidity", "humidity ratio" and "enthalpy".
If you enter the any 2 of the items and tap “ENTER”, the app is automatically calculate other items.
You can refer to more items(plus 6 items) by use the app and sister app "HumidCalc" in combination(additional features since version 1.0.7).
