What is Kelvin to Celsius Conversion?
Kelvin (K) and Celsius (°C) are both temperature scales used in science and everyday life. Kelvin to Celsius conversion converts an absolute temperature value in Kelvin into degrees Celsius.
If you’re wondering is kelvin the same as celsius, they are not the same scale. They use the same size degree step (a change of 1 K equals a change of 1°C), but Kelvin starts at absolute zero while Celsius is offset so that water freezes at 0°C.
People often ask where is kelvin used in the world and why kelvin is used. Kelvin is the SI base unit for temperature and is widely used in science, physics, chemistry, engineering, and research because it avoids negative absolute temperatures and works cleanly in thermodynamic equations.
This temperature converter kelvin to celsius page includes the kelvin to celsius converter formula, examples, and a chart for quick reference.
Kelvin to Celsius Formula
To convert Kelvin to Celsius, subtract 273.15. This is the standard kelvin to celsius conversion formula and kelvin to celsius equation used in calculators.
This is the kelvin to c formula (kelvin to celsius conversion equation).
Use this for the reverse conversion.
So 0 K equals −273.15°C (absolute zero).
So 300 K equals 26.85°C.
A change of 1 Kelvin equals a change of 1 Celsius degree (same step size).
Convert Celsius to Kelvin by adding 273.15.

Frequently Asked Questions
Subtract 273.15. The formula is °C = K - 273.15.
°C = K - 273.15.
No. They have the same step size, but Kelvin starts at absolute zero, while Celsius is offset so water freezes at 0°C.
A 1°C change equals a 1 K change. They differ by an offset of 273.15, not by scale size.
Kelvin is used globally in science and engineering as the SI base unit for temperature.
Kelvin is an absolute temperature scale used in thermodynamics and scientific equations because it starts at absolute zero and avoids negative absolute temperatures.
Subtract 273.15 from the Kelvin value to get Celsius.
