About Fahrenheit and Kelvin
- Fahrenheit
- Degrees Fahrenheit use 180 intervals between the traditional water freezing and boiling reference points. Imperial or US customary measurement, depending on the unit.
- Kelvin
- The kelvin is the SI base unit of thermodynamic temperature and begins at absolute zero. International System of Units (SI) or an SI-derived metric unit.
Precision and common mistakes
Celsius/Fahrenheit conversion applies both 5/9 scaling and a 32-degree offset. Kelvin values are written without a degree symbol. The calculator keeps the full catalogued factor internally and rounds only the displayed value.
- A temperature difference and an absolute temperature use different offset rules.
- Negative kelvin values are outside the physical thermodynamic scale.
- Keep the original value and unit together when copying a result, especially when specifications use several measurement systems.
