Kelvin is the base unit of temperature in the International System of Units (SI). Unlike Celsius, Kelvin is an absolute scale starting at absolute zero.

The Absolute Formula:

K = °C + 273.15

Kelvin is primarily used in the physical sciences to measure absolute temperatures, where 0 K represents the theoretical absence of all thermal energy.
