How to Convert Kelvin to Celsius
To convert Kelvin (K) to Celsius (°C), use the formula: °C = K − 273.15.
For example, to convert 5 K to °C: 5 K = -268.15 °C. Similarly, 10 K = -263.15 °C, 25 K = -248.15 °C, and 100 K = -173.15 °C.
To convert in the other direction, 1 °C = 274.15 K. Simply enter your value in either field above for instant bi-directional conversion.
What is a Kelvin?
Kelvin (K) is the SI base unit of temperature, starting at absolute zero (−273.15 °C). Kelvin is used in science, engineering, and color temperature for lighting and displays.
What is a Celsius?
Celsius (°C) is a temperature scale where water freezes at 0° and boils at 100° at standard pressure. Celsius is used by most countries worldwide for weather, cooking, and science.
