What is the equation to convert Kelvin to Celsius?

The conversion from Kelvin to Celsius is correctly represented by the equation C = K - 273. This formula reflects the relationship between the two temperature scales, where Celsius is derived from Kelvin by subtracting 273, which is the offset between the two scales at absolute zero.

In the Kelvin scale, 0 K corresponds to -273.15 °C. Therefore, when converting a temperature given in Kelvin to Celsius, you need to subtract approximately 273.15 from the Kelvin temperature. However, in many cases, the equation is simplified to C = K - 273 for practical purposes, rounding off the decimal.

Hence, by using the correct equation, you can accurately determine the Celsius equivalent of a temperature provided in Kelvin, facilitating the understanding of measurements in different temperature scales.
