0 kelvin to celsius: Result is -273.15°C

Converting 0 kelvin to celsius results in -273.15 degrees Celsius. This is because kelvin and Celsius are related temperature scales, where 0 kelvin represents absolute zero, the lowest possible temperature, corresponding to -273.15°C. Hence, 0 kelvin equals -273.15°C.

Conversion Explanation

The conversion from kelvin to celsius involves subtracting 273.15 from the kelvin value. Since the kelvin scale starts at absolute zero, which is -273.15°C, subtracting 273.15 from any kelvin temperature gives its equivalent in Celsius. For example, 0 K minus 273.15 equals -273.15°C. This simple formula accounts for the difference in starting points of the two scales.
