Definition

Kelvin is the SI base unit for temperature, symbolized as K. It measures absolute temperature starting from absolute zero.

Zero Kelvin (0 K) is known as absolute zero, the point where all molecular motion ceases.
The Kelvin scale does not use degrees; it is simply 'Kelvin'.
The freezing point of water on the Kelvin scale is 273.15 K.
To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.
The Kelvin scale is essential for scientific calculations involving thermodynamics and kinetic theory.

The lowest possible temperature, 0 K, where molecular motion theoretically stops.

Thermodynamics: The branch of physics that deals with heat, work, and forms of energy.

A theory that explains the macroscopic properties of gases by considering their molecular composition and motion.
