Celsius to Kelvin calculator (°C to K)

Convert celsius to kelvin (°C to K) by typing the amount of celsius in the input field below and then clicking in the "Convert" button. If you want to convert from kelvin to celsius, you can use our kelvin to celsius converter.


Formula used to convert °C to K:

F(x) = x + 273.15

For example, if you want to convert 1 °C to K, just replace x by 1 [°C]:

1 °C = 1 + 273.15 = 274.15 K


  1. Add 273.15 to the temperature expressed in Celsius degrees.
  2. The result will be expressed in Kelvin.

About Celsius (°C)

The Celsius scale (symbol °C), also known as the centigrade scale, is a temperature scale used to measure temperature defined by the International System of Units (SI). It is used by all countries except the United States, the Bahamas, Belize, the Cayman Islands and Liberia.

Since 1743, the Celsius scale is based on 0 °C for the freezing point of water and 100 °C for the boiling point of water at 1 atm pressure.

About Kelvin (K)

The Kelvin is the base unit of temperature in the International System of Units (SI). The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero (the temperature at which all thermal motion ceases). The symbol used to express kelvin is K.

Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or written as a degree because it’s not a relative scale, but an absolute one. A degree is a change in temperature that is measured against a scale. Therefore, because there is no negative values for Kelvin scale, then the degree symbol is not used.
