Question: what is the relation between celsius and kelvin scale of temperature?
Answer: Kelvin Scale Degrees Celsius (°C) and kelvins (K) have the same magnitude. The only difference between the scales is their starting points: 0 K is "absolute zero," while 0°C is the freezing point of water. One can convert degrees Celsius to kelvins by adding 273.15; thus, the boiling point of water, 100°C, is 373.15 K.
