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)
