About converting Kelvin to Celsius

Converting Kelvin to Celsius is a common temperature conversion. One kelvin (K) equals -272.1 celsius (°C). Kelvin is the SI unit for thermodynamic temperature, used in physics and engineering.

This conversion is commonly needed for weather and travel planning, cooking and baking, scientific experiments. Celsius is used in most countries worldwide and in all scientific applications.

To put kelvin in perspective: absolute zero (0 K). In celsius, common references include water freezes (0 °C).

Did you know?

0 Kelvin (absolute zero) is theoretically the lowest possible temperature, where all molecular motion stops. It has never been fully achieved in a laboratory.

Real-world examples
Kelvin (K)
  • absolute zero (0 K)
  • liquid nitrogen (-196 °C or 77 K)
  • the Sun's surface (about 5,778 K)
Celsius (°C)
  • water freezes (0 °C)
  • a comfortable room (21 °C)
  • water boils (100 °C)
Did you know?

The Celsius scale was invented by Swedish astronomer Anders Celsius in 1742, but he originally set 0° as boiling and 100° as freezing — it was later reversed.

Common uses for temperature conversion

Frequently asked questions
How do you convert Kelvin to Celsius?
To convert Kelvin to Celsius, use the formula: °C = K − 273.15. For example, 5 K = -268.1 °C.
What is 1 Kelvin in Celsius?
1 K is equal to -272.1 °C.
How many kelvin are in 1 celsius?
1 °C is equal to 274.1 K. To convert Celsius back to Kelvin, multiply the celsius value by 274.1.
When would I need to convert kelvin to celsius?
This conversion is commonly needed for weather and travel planning, cooking and baking, scientific experiments, HVAC and home heating, industrial processes. Kelvin is the SI unit for thermodynamic temperature, used in physics and engineering. Celsius is used in most countries worldwide and in all scientific applications.
What does 5 kelvin look like in real life?
For reference, some common kelvin measurements include: absolute zero (0 K); liquid nitrogen (-196 °C or 77 K); the Sun's surface (about 5,778 K). So 5 K (-268.1 °C) gives you a practical sense of scale.
