Which expression represents Kelvin to Celsius temperature conversion?

Explanation:
Kelvin and Celsius are the same temperature scale shifted by a constant amount. The Kelvin value is the Celsius value plus 273 (more precisely 273.15). To convert from Kelvin to Celsius, you remove that offset by subtracting 273: Celsius equals Kelvin minus 273 (approximately 273.15). For example, if Kelvin is 300, Celsius is about 27. If Celsius is 0, Kelvin is about 273. This is the form that directly converts Kelvin to Celsius. The alternate form that solves for Kelvin from Celsius is the same relationship rearranged, not the direction the question asks for.
