About Kelvin and Celsius
Both the Kelvin (K) and the Celsius (°C) measure temperature. Because temperature scales have different zero points, converting between them requires both a scale factor and an offset rather than a single multiplication. Enter any value above to convert instantly, or use the formula and reference table below.
Unit definitions
- Kelvin (K)
- The Kelvin (K) is a unit of temperature. The Kelvin scale starts at absolute zero (0 K), the coldest possible temperature; water freezes at 273.15 K.
- Celsius (°C)
- The Celsius (°C) is a unit of temperature. On the Celsius scale water freezes at 0° and boils at 100° at standard pressure.
Frequently asked questions
- How do you convert Kelvin to Celsius?
- Temperature scales differ by both scale and offset, so you apply a formula rather than a single factor. For example, 1 Kelvin equals -272.15 Celsius. Enter a value in the converter above for an instant result.
