STP, Rate and Volume Correction Calculators

Here are some useful calculators for correcting volumes and rates to and from STP, and for correcting flow rates for the presence of water vapor in respirometry systems using excurrent flow measurement.

Correct volume or flow rate to “dry” if ambient relative humidity,
temperature and barometric pressure are known

This calculator uses the Arden Buck equation (see water vapor calculators).

Enter volume or rate to be “dried”*:

Enter ambient temperature in ^oC:

Enter relative humidity in percent:

Enter barometric pressure in kPa:

Water vapor pressure (kPa) is:

“Dry” volume or rate is:

“Dry” correction factor is:

* Optional parameter
