Kelvin to Celsius

K = ? °C

This converter makes instant conversions from Kelvin (K) to Celsius (°C). It also provides the conversion steps. To use the converter, please provide a value in the input field. The converter will begin making conversions as the values are being typed in.

Kelvin and Celsius are the two units of temperature used within the International System of Units (SI) with Kelvin being the primary unit. The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its zero point. The Kelvin scale is largely used in the sciences and engineering, while in most countries Celsius remains the dominant scale outside of these fields and in the United States the Fahrenheit scale is still widespread.

How to convert Kelvin to Celsius

The scale of the kelvin is the same as the Celsius scale, meaning that a change of 1°C is the same as a change of 1 K. To convert from Kelvin to Celsius, just subtract 273.15 from the Kelvin value:

°C = K - 273.15

For example, 500K can be converted from Kelvin to Celsius as:

500K = (500 - 273.15)°C = 226.85°C
