About Celsius and Kelvin
- Celsius
- Degrees Celsius use the same interval size as kelvins, with zero set at 273.15 K. International System of Units (SI) or an SI-derived metric 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
Temperature conversions include an offset as well as a scale factor. Kelvin values are written without a degree symbol. The calculator keeps the full catalogued factor internally and rounds only the displayed value.
- Temperature values cannot be converted by a simple unit factor when scale origins differ.
- 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.
