About the degree Celsius
Water freezes at 0°, boils at 100° at standard pressure.
About the kelvin
Absolute temperature scale. Same size as Celsius, 0 K = absolute zero.
How degree Celsius to kelvin conversion works
Temperature scales are affine: the result needs both a scale factor and a zero-point offset. That is why °C to K cannot be reduced to a simple percentage change.
The right unit depends on the convention used by your industry, country, instrument, or source document.

Frequently asked questions
Frequently Asked Questions
How do I convert degree Celsius to kelvin?
Multiply the degree Celsius value by 274.15 to get it in kelvin. For example, 10 °C = 283.15 K.
What is 1 °C in K?
1 °C = 274.15 K.
What is 100 °C in K?
100 °C = 373.15 K.
What is the formula?
Temperature is an affine quantity. The formula depends on the source and target scales; °C → K uses: T(K) = T(°C) × 1 + 273.15, then applies the inverse on the other side.
