The Kelvin is the SI unit for temperature. $0\,\mathrm{K}$ is defined as absolute zero, the theoretical temperature at which there is no movement. It is defined by setting the Boltzmann constant to $1.380649 \cdot 10^{-23} \frac{\text{J}}{\text{K}}$, given the original definition of the meter, the kilogram, and the second.
