How to convert degrees Celsius to kelvins

Temperature scales start at different zero points, so you can't just multiply. Use this formula:

K = °C + 273.15

Example

Let's convert 37 degrees Celsius to kelvins:

37 °C = 310.15 K

Going the other way

1 kelvin = -272.15 degrees Celsius. Use our kelvins to degrees Celsius converter.
