The new Vaisala humidity Calculator is a web based software tool that allows the user to calculate several humidity parameters from a known humidity value. One can quickly convert between units, and see the effects of changing ambient conditions, like temperature and pressure. Relative humidity, dewpoint / frostpoint, absolute humidity, water content, mixing ratio, vapour pressure and parts per million can be calculated easily and quickly with the calculator.

The most commonly used units for each parameter have been included and can be changed during the calculation.

By changing the ambient conditions (temperature and pressure), their effect on each calculated parameter can be seen.

In addition to the online calculator, a downloadable version is also available from the website.
