Conversion formula

Celsius to Kelvin Formula

This formula converts degrees Celsius into kelvins using the temperature category’s normalized conversion strategy.

Formula

Kelvin = Celsius × 1 + 273.15

Variables

Celsius
The input value measured in degrees Celsius.
Kelvin
The resulting value measured in kelvins.

Worked example

For 100 degrees Celsius: Kelvin = 100 × 1 + 273.15 = 373.15 kelvins.

Notes

  • Celsius uses the Metric measurement system.
  • Kelvin uses the SI measurement system.
  • The converter calculates with full precision before formatting results.

Common mistakes

  • Using kelvins as the input instead of degrees Celsius.
  • Rounding the intermediate value before completing the calculation.
  • Mixing units from a different measurement category.

Frequently asked questions

What is the Celsius to Kelvin formula?

Use Kelvin = Celsius × 1 + 273.15.

How do I convert degrees Celsius to kelvins?

Apply the formula to the celsius value, then read the result in kelvins.

Is this formula valid for every value?

Yes. It is derived from the normalized conversion strategy for the temperature category.
