The GE Moisture Calculator converts a known Dew point and a known pressure to PPMv (Parts per Million, volume basis) for Ideal Gases, as well as converting a Dew point and Temperature to RH (Relative Humidity).


- Dew / Frost Point (°C or °F)

- Dew point values (-110 °C to +60°C or -166°F to 140°F)

- Ambient Temperature

- Gauge Pressure (Pa, kPa, psig, bar, atm)

- Temperature (Celsius, Fahrenheit)

- %RH Relative Humidity

- Moisture Content PPMv

Best dew point and moisture calculator I've found

The flexibility and finesse of the user interface makes this app stand out over the handful of similar apps, both free and paid. The app uses a simple numeric keyboard, rather than the standard alphanumeric, which makes data entry far easier. The ease of changing units of measurement is also a big plus. I use the dew point calculator part of it most often, to estimate the moisture content of indoor air indoors as temperature and RH fluctuate with the heating system.

Simple interface but tough to see input fields & result

Great that they utilize the 10-key instead of the full keyboard to enter numbers. But the font is tiny. Plus, light blue text on a white background makes it hard to read!

Great Transformer App

If you work with dewpointing a power transformer you need this app to find the moisture of your transformer fast.
