Unit Definitions
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.
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.
Historical Context
The Kelvin scale was proposed by William Thomson (Lord Kelvin) in 1848. The Celsius scale was proposed by Swedish astronomer Anders Celsius in 1742, though it was initially reversed (0° was boiling, 100° was freezing) before being standardized in its current form.
