Celsius | [°C] = ([°R] − 491.67) × 5⁄9 | [°R] = [°C] × 9⁄5 + 491.67 |
Fārenhād | [°F] = [°R] − 459.67 | [°R] = [°F] + 459.67 |
Kelvin | [K] = [°R] × 5⁄9 | [°R] = [K] × 9⁄5 |
For temperature intervals rather than specific temperatures, 1 °R = 1 °F = 5⁄9 °C = 5⁄9 K Comparisons among various temperature scales |

- ↑ For Vienna Standard Mean Ocean Water at one standard atmosphere (101.325 kPa) when calibrated solely per the two-point definition of thermodynamic temperature. Older definitions of the Celsius scale once defined the boiling point of water under one standard atmosphere as being precisely 100 °C. However, the current definition results in a boiling point that is actually 16.1 mK less. For more about the actual boiling point of water, see VSMOW in temperature measurement.
