Kelvin to Celsius
Convert kelvin (K) to celsius (°C).

About this conversion

Convert between degrees Celsius (°C), degrees Fahrenheit (°F), and kelvin (K). Unlike linear units, temperature scales have different zero points, so conversions require offset formulas, not simple multiplication. Kelvin (K) is the SI base unit; 0 K is absolute zero (−273.15 °C).

This temperature converter transforms values from Kelvin (K) to Celsius (°C). Temperature scales have different zero points, so conversion uses an offset formula, not a simple multiplier.

The kelvin (K) is the SI base unit of thermodynamic temperature; 0 K is absolute zero. Temperature intervals in K equal those in °C.

Degrees Celsius (°C) is a metric temperature scale where 0 °C is the freezing point of water and 100 °C is its boiling point at standard pressure.

Kelvin to Celsius Formula

°C = K − 273.15

How to convert Kelvin to Celsius?

°C = K − 273.15

The conversion formula transforms K to °C. Values are first converted to kelvin (K), the SI base unit, then to the target scale, which avoids rounding errors from chained offset formulas. A change of 1 °C equals a change of 1 K, but 0 °C ≠ 0 K.

Example: Convert 10 K to °C

-263.15 °C = 10 K − 273.15 = -263.15 °C
