Kelvin to Celsius Converter

Convert an ordinary kelvin temperature into Celsius. The input is a kelvin reading and the output may be a negative Celsius temperature.

How to use Kelvin to Celsius Converter

1. Enter Kelvin. 2. Ordinary temperature conversion on the stated Celsius/Fahrenheit/Kelvin basis, subject to its supported lower bound and output range. 3. Select Convert or press Enter from a single-line field. In multiline text fields, Enter inserts a line break. 4. Select Copy result to copy the answer, or Reset to clear the form and result.

Why use this tool?

Use Kelvin to Celsius Converter when you need celsius. Ordinary temperature conversion on the stated Celsius/Fahrenheit/Kelvin basis, subject to its supported lower bound and output range.

How the calculation works

Celsius = Kelvin − 273.15. The Celsius and kelvin scales have equal-sized temperature intervals and an exact 273.15 offset for readings. Ordinary temperature conversion on the stated Celsius/Fahrenheit/Kelvin basis, subject to its supported lower bound and output range.

Example

Worked example: Kelvin = 300. Result: 26.85 °C.

Practical tip

Enter kelvin with no degree symbol: use K rather than °K. Negative kelvin values are outside this tool’s ordinary temperature scope.
