How do I convert degrees Celsius to kelvins?

Use the formula K = °C + 273.15. For example, 20 °C = 293.15 K.

What is 37 °C in kelvins?

37 degrees Celsius equals 310.15 kelvins.

How do I convert kelvins back to degrees Celsius?

Use the reverse Kelvin to Celsius converter: °C = K − 273.15.

How to convert degrees Celsius to kelvins

Temperature scales do not share the same zero point, so you cannot simply multiply. Use this formula:

K = °C + 273.15

Examples

20 °C = 293.15 K
37 °C = 310.15 K
100 °C = 373.15 K

About the units

Degree Celsius (°C)

The Celsius scale sets 0 °C at the freezing point of water and 100 °C at its boiling point (at standard pressure). It is used for weather and cooking in almost every country.

Kelvin (K)

The kelvin is the SI base unit of temperature. 0 K is absolute zero, and a change of 1 K equals a change of 1 °C. It is used in science and engineering.
