The Kelvin Converter supports 8 different temperature units. This makes it possible to convert between kelvins [K] and other temperature units as desired. All values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.
Conversion of kelvins
To convert between kelvins [K] and other temperature units, an individual calculation method is required. This can be determined using a conversion table. However, the tables are relatively large and confusing, which makes them difficult to understand for inexperienced users. The following tool provides a solution to this problem by allowing the calculation method for converting between kelvins [K] and other temperature units to be queried directly from the table.

Convert kelvin and degrees Celsius
A temperature of 0°C corresponds to 273.15 kelvins. To convert degrees Celsius [°C] to kelvins [K] simply add 273.15 to the degree value. To convert kelvins [K] to degrees Celsius [°C] subtract 273.15 from the kelvins value.
- Degrees Celsius [°C] = kelvins [K] – 273.15
- Kelvins [K] = degrees Celsius [°C] + 273.15
Convert kelvin and Fahrenheit
To convert from kelvins [K] to degrees Fahrenheit [°F] use the following formula: ((K – 273.15) * 1.8) + 32. To convert from degrees Fahrenheit [°F] to kelvins [K] use the following formula: K = ((°F – 32) * 5⁄9) + 273.15. For both formulas, it is important to note that the values within the brackets must be calculated first.
- Degrees Fahrenheit [°F] = ((kelvins [K] – 273.15) * 1.8) + 32
- Kelvins [K] = ((degrees Fahrenheit [°F] – 32) * 5⁄9) + 273.15
