Notes

• Values are given in terms of temperature necessary to reach the specified pressure.
• Valid results within the quoted ranges from most equations are included in the table for comparison.
• A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
• Ref. SMI uses temperature scale ITS-48. No conversion was done, which should be of little consequence however.
• The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere.
• log refers to log base 10
• (T/K) refers to temperature in Kelvin (K)
• (P/Pa) refers to pressure in Pascal (Pa)
