The Kelvin scale is an absolute temperature scale named after the Scottish physicist William Thomson, 1st Baron Kelvin. It is commonly used in scientific and engineering applications where an absolute temperature reference is required. The Kelvin scale starts at absolute zero, the point at which all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15 K, and the boiling point is 373.15 K.


Celsius is a unit of temperature measurement that is part of the metric system. It is named after the Swedish astronomer Anders Celsius, who developed the scale. The Celsius scale sets the freezing point of water at 0 degrees and the boiling point at 100 degrees under standard atmospheric pressure. It is widely used in scientific and everyday contexts around the world.
