Kelvin to Celsius calculator (K to °C)

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


Formula used to convert K to °C:

F(x) = x - 273.15

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

1 K = 1 - 273.15 = -272.15 °C


  1. Subtract 273.15 from the temperature expressed in Kelvin.
  2. The result will be expressed in Celsius degrees.

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.

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.
