When you need this conversion

Kelvin is the SI base unit for temperature and starts at absolute zero, so it is what physics and chemistry coursework requires — gas law calculations break if you use Celsius. Kelvin also describes the color temperature of light bulbs, where 2700 K reads as warm white and 6500 K as daylight.

The formula

°C = K − 273.15

Temperature scales do not share a common zero point, so converting kelvin to degrees Celsius requires both a scaling step and an offset rather than a single multiplication.
