Use this celsius to kelvin converter to change a celsius measurement into its kelvin equivalent. Enter a number in the calculator above and the result updates instantly.
Temperature conversions are often used for weather, cooking, appliance settings, science, engineering, and travel between countries that use different temperature scales.
What is a celsius?
Celsius is a metric temperature scale used in most countries and in scientific contexts. Water freezes at 0 C and boils at 100 C at standard pressure.
What is a kelvin?
Kelvin is an absolute temperature scale used in science and engineering. Zero kelvin represents absolute zero.
Celsius to Kelvin Converter formula
To convert degrees Celsius to kelvins, use the formula below.
Because Celsius and Kelvin use different temperature scales, the conversion uses a formula with both a scale change and an offset.
How to convert celsius to kelvin
Start with the celsius value, apply the formula, and round the result only after the calculation is complete.
Example: 10 C = 283.15 K.
- 32 C = 305.15 K
- 68 C = 341.15 K
- 100 C = 373.15 K
Manual conversion steps
- Write down the value in degrees Celsius.
- Use the conversion formula: K = C + 273.15.
- Calculate the result in kelvins.
- Round the answer to the number of decimal places you need.
For quick checking, the converter above performs the same calculation automatically.
Common celsius to kelvin use cases
This conversion is useful in practical situations where measurements need to move between different unit systems or audiences.
- Convert degrees Celsius to kelvins for weather forecasts, cooking temperatures, appliance settings, science, and travel.
- Temperature conversions are especially useful when moving between US customary and metric everyday references.
Common mistakes when converting celsius to kelvin
These are the most common issues to watch for when doing this conversion by hand.
- Do not treat temperature conversion as simple multiplication. Temperature scales often require an offset.
- Check whether the input is already in the correct temperature scale before applying the formula.
