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.

Kelvin to Celsius =
°C = K - 273.15

This is the kelvin to c formula (kelvin to celsius conversion equation).

Celsius to Kelvin =
K = °C + 273.15

Use this for the reverse conversion.

273.15
= Offset between Kelvin and Celsius scales
Example: 0 kelvin to celsius
0 - 273.15 = -273.15°C

So 0 K equals −273.15°C (absolute zero).

Example: convert kelvin to celsius calculator
300 K - 273.15 = 26.85°C

So 300 K equals 26.85°C.

How many kelvins are in 1 celsius?
1 K change = 1°C change

A change of 1 Kelvin equals a change of 1 Celsius degree (same step size).

How many kelvins are in celsius?
K = °C + 273.15

Convert Celsius to Kelvin by adding 273.15.

Frequently Asked Questions

How to calculate kelvin to celsius?

Subtract 273.15. The formula is °C = K - 273.15.

What is the kelvin to c formula?

°C = K - 273.15.

Is kelvin the same as celsius?

No. They have the same step size, but Kelvin starts at absolute zero, while Celsius is offset so water freezes at 0°C.

How many kelvins are in 1 celsius?

A 1°C change equals a 1 K change. They differ by an offset of 273.15, not by scale size.

Where is kelvin used in the world?

Kelvin is used globally in science and engineering as the SI base unit for temperature.

Why do we use kelvin instead of celsius / why is kelvin used instead of celsius?

Kelvin is an absolute temperature scale used in thermodynamics and scientific equations because it starts at absolute zero and avoids negative absolute temperatures.

How to get kelvin to celsius?

Subtract 273.15 from the Kelvin value to get Celsius.
