This example problem illustrates the method to convert temperatures from Kelvin to Celsius.

Kelvin To Celsius (K to C) Problem:

What is the temperature in °C of a 256 K object?


The conversion formula for °C to K is

TC = (TK) - 273

TC = 256 - 273
TC = -17 °C


The temperature in Celsius of a 256 K object is -17 °C.
