Unit Definitions
Celsius
The Celsius scale (symbol: °C) is a temperature scale used by the International System of Units (SI). It defines 0°C as the freezing point of water and 100°C as the boiling point of water at standard atmospheric pressure.
Kelvin
The Kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI). It is an absolute temperature scale where zero represents absolute zero, the theoretical point at which all thermal motion ceases.
Historical Context
The Celsius scale was proposed by Swedish astronomer Anders Celsius in 1742. The Kelvin scale was proposed by William Thomson (Lord Kelvin) in 1848, based on the Celsius scale but starting from absolute zero.
