degree Kelvin [K] to degree Celsius [C] Converter

Quick Reference

1 degree Kelvin (K) = -272.15 degree Celsius (C)

1 degree Celsius (C) = 274.15 degree Kelvin (K)

How to Convert degree Kelvin to degree Celsius

1 K = -272.15 C
1 C = 274.15 K

To convert degree Kelvin to degree Celsius, divide the value by 274.15 (equivalently, multiply by -272.15). To convert degree Celsius back to degree Kelvin, multiply by 274.15.

Example: convert 10 K to C:
10 K = 10 x -272.15 = -2721.5 C

↔ Convert degree Celsius to degree Kelvin

degree Kelvin

Definition: Degree Kelvin (K) is the base unit of temperature in the International System of Units (SI). It is an absolute thermodynamic temperature scale where 0 K is absolute zero, the point at which all molecular motion ceases.

History/origin: The Kelvin scale was proposed by William Thomson, 1st Baron Kelvin, in 1848. It is based on the Celsius scale, but with its zero point at absolute zero (-273.15 °C).

Current use: Degree Kelvin is primarily used in scientific and engineering applications where absolute temperature is required, such as thermodynamics, astrophysics, and low-temperature physics.

degree Celsius

Definition: Degree Celsius (°C) is a unit of temperature on the Celsius scale, which is defined so that the freezing point of water is 0 °C and the boiling point is 100 °C at standard atmospheric pressure.

History/origin: The Celsius scale was originally proposed in 1742 by the Swedish astronomer Anders Celsius. He originally defined 0 °C as the boiling point of water and 100 °C as the freezing point, but this was later reversed to its current definition.

Current use: Degree Celsius is the standard unit of temperature used in most of the world, except for the United States and a few other countries. It is used in scientific research, weather reporting, and everyday life.
