What is the formula to convert Kelvin to Celsius?

Kelvin and Celsius use the same size degree, but their zero points differ by 273.15. To move from Kelvin to Celsius you subtract that offset: C = K − 273.15. This matches the absolute zeros: 0 K corresponds to −273.15 °C, and 273.15 K corresponds to 0 °C. For example, 300 K is 26.85 °C. Using the opposite sign or adding the offset would misalign with where the scales start, so those forms don’t yield the correct Celsius value.
