About converting Celsius to Kelvin

Converting Celsius to Kelvin is a common temperature conversion. One celsius (°C) equals 274.1 kelvin (K). Celsius is used in most countries worldwide and in all scientific applications.

This conversion is commonly needed for weather and travel planning, cooking and baking, scientific experiments. Kelvin is the SI unit for thermodynamic temperature, used in physics and engineering.

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

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.

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

Common uses for temperature conversion
