The Kelvin scale is a temperature scale used in the sciences and engineering. It is one of the seven base units in the International System of Units (SI) and is named after the physicist William Thomson, 1st Baron Kelvin. The Kelvin scale is based on the concept of absolute zero, the theoretical point at which the motion of particles that make up matter ceases completely.
