About kelvins and degrees Celsius

Kelvin (K)

The kelvin is the SI base unit of thermodynamic temperature; 0 K is absolute zero and one kelvin step equals one degree Celsius step. It is used in physics, chemistry and engineering.

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; 0 °C equals 273.15 K. It is used for weather, cooking and science in most countries.

Both are units of temperature; the base unit used internally is K.

Notes

K to °C FAQs

How do I convert kelvins to degrees Celsius?

Use the formula °C = K − 273.15. For example, 25 K is -248.15 °C. You can also type any value into the converter above and the answer updates as you type.

What is 1 kelvin in degrees Celsius?

1 K = -272.15 °C (temperature scales are offset, so this is not a simple ratio and does not apply to other values). To go the other way, use the degrees Celsius to kelvins converter.

What is 25 K in degrees Celsius?

25 K = -248.15 °C, rounded to 6 significant digits. Change the value in the converter above for any other amount.

What is 273 K in degrees Celsius?

273 K = -0.15 °C, rounded to 6 significant digits.

What is the difference between kelvins and degrees Celsius?

The kelvin is the SI base unit of thermodynamic temperature; 0 K is absolute zero and one kelvin step equals one degree Celsius step. It is used in physics, chemistry and engineering. The Celsius scale sets 0 °C at the freezing point of water and 100 °C at its boiling point at standard pressure; 0 °C equals 273.15 K. It is used for weather, cooking and science in most countries.

Is there a lowest possible temperature?

Yes, absolute zero: 0 K, which is -273.15 °C or -459.67 °F. The converter rejects values below it.
