Temperature =

Dewpoint =

Relative Humidity =

Determine one of temperature, dewpoint, and relative humidity, given the other two.

When you click New, everything is set to zero and you must enter two of the values. As soon as the second one is entered, the third is computed. Otherwise, any time you update one of the values, you then press the green Equals button of the value you want to recalculate.

Click New then enter 90 for the temperature and 70 for the dewpoint. The humidity will be calculated: 51.8%.

Now, change the humidity to 60% and then have dewpoint recalculated: 74.3F.
