How to convert Kelvin to degrees Celsius
Converting Kelvin to degrees Celsius means moving between two temperature scales using the formula °C = K − 273.15. Because temperature scales start from different zero points, the conversion involves both scaling and an offset rather than a single multiplier. Type any value above and the result updates instantly, entirely in your browser.
Turn an absolute temperature in Kelvin from physics or chemistry into familiar Celsius. Knowing how to move between Kelvin and degrees Celsius is useful whenever measurements are given in one system but you need them in the other — for shopping, travel, study, cooking, engineering or simply comparing figures from different countries.
The reference table below lists common Kelvin values already converted to degrees Celsius, so you can read off everyday amounts at a glance without typing. For the opposite direction, use the Celsius to Kelvin Converter, which reverses the calculation exactly.

Frequently asked questions
How do I convert Kelvin to degrees Celsius?
Use the formula °C = K − 273.15. Enter your temperature above and the converter applies it instantly.
How many degrees Celsius are in one Kelvin?
Temperature scales do not have a single ratio because they use an offset. Use the formula °C = K − 273.15 to convert any value exactly.
Is this Kelvin to Celsius converter accurate?
Yes. It uses the exact conversion formula, so results are precise. Values shown in the table are rounded for readability.
How do I convert degrees Celsius back to Kelvin?
Use our Celsius to Kelvin Converter for the reverse direction.
