Answer

To convert from Kelvin to Celsius, subtract 273.15 from the Kelvin temperature. The formula is: °C = K - 273.15. For example, if you have 300 K, you would calculate 300 - 273.15 = 26.85°C. This conversion works because the Kelvin and Celsius scales use the same unit size, but they start at different points Kelvin begins at absolute zero while Celsius begins at the freezing point of water.
