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.

Ambient temperature and barometric pressure to STP

Enter volume or rate for correction to STP*:

Enter temperature in oC:

Enter barometric pressure in kPa:

Click this button to calculate STP correction:

STP corrected volume or rate:

STP correction factor is:

* Optional parameter

STP to ambient temperature and barometric pressure

Enter volume or rate at STP*:

Enter temperature in oC:

Enter barometric pressure in kPa:

Click this button to calculate ambient correction:

Volume or rate corrected from STP:

STP to ambient correction factor is:

* Optional parameter

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:

Click this button to correct to "dry":

Water vapor pressure (kPa) is:

"Dry" volume or rate is:

"Dry" correction factor is:

* Optional parameter
