Kelvins to Degrees Celsius Converter

Subtract 273.15 from a kelvin value to get degrees Celsius.

300 K = 26.85 °C

Convert degrees Celsius to kelvins instead

Formula

°C = K − 273.15

Worked example

Convert 300 kelvins to degrees Celsius

  1. Use °C = K − 273.15
  2. Substitute 300 K: 26.85 °C

300 K = 26.85 °C

Good to know

Values below 0 K are impossible, so the converter rejects them. Some reference points: 77 K is liquid nitrogen (−196.15 °C), 273.15 K is the freezing point of water, 293 K is a typical lab “room temperature”, and the Sun’s surface is about 5,800 K. Color temperatures of light bulbs (2,700 K warm white, 6,500 K daylight) are also in kelvins.

About these units

Kelvin (K)
The SI unit of temperature. 0 K is absolute zero; 0 °C is exactly 273.15 K. Kelvin is written without a degree sign.
Degree Celsius (°C)
Water freezes at 0 °C and boils at about 100 °C at sea-level pressure. A change of 1 °C equals a change of 1 K.
