Equation of state

The uncertainties of the equation of state are generally 0.1% in density and 2% in the speed of sound, except in the critical region and high pressures.

Important Information About This Data

The data above are from an older version of the NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP version 7). We will be updating our site to use the newer version (version 9.1) of this database in the the next couple of months. Information on REFPROP version 9.1 can be found here. REFPROP version 9.1 includes additional data and features not available from this site.
