Conversion FactorsóI/P Units to SI Units  \nProperties listed in the following thermodynamic tables in I/P units can be converted to SI units using the conversion factors shown below. Please note that in converting enthalpy and entropy from I/P to SI units, a change in reference states must be included (from H = 0 and S = 0 at –40°F for I/P units to H = 200 and S = 1 at 0°C for SI units). In the conversion equation below, H (ref) and S (ref) are the saturated liquid enthalpy and entropy at –40°C.
