About degrees Celsius and kelvins

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.

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.

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

Notes

°C to K FAQs

How do I convert degrees Celsius to kelvins?

Use the formula K = °C + 273.15. For example, 25 °C is 298.15 K. You can also type any value into the converter above and the answer updates as you type.

What is 1 degree Celsius in kelvins?

1 °C = 274.15 K (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 kelvins to degrees Celsius converter.

What is 25 °C in kelvins?

25 °C = 298.15 K, rounded to 6 significant digits. Change the value in the converter above for any other amount.

What is 20 °C in kelvins?

20 °C = 293.15 K, rounded to 6 significant digits.

What is the difference between degrees Celsius and kelvins?

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. 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.

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.
