The Kelvin scale, also known as the absolute thermodynamic temperature scale, is a thermodynamic temperature scale where zero is absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The Kelvin scale is the primary unit of measurement in the physical sciences, but is often used in conjunction with the Celsius scale, which sets its zero at the freezing point of water and its scale at the triple point of water. The Kelvin scale is named after Lord Kelvin, who first proposed an absolute thermodynamic temperature scale in 1848. The Kelvin scale is an absolute scale, meaning it does not have a negative side. The unit of the Kelvin scale is the kelvin, which is defined as the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. The Kelvin scale is used in scientific and engineering applications, as well as in the fields of physics, chemistry, and materials science. It is also used in the study of thermodynamics, statistical mechanics, and quantum mechanics. The Kelvin scale is widely used in international standards and conventions, and is recognized as the standard temperature scale by the International System of Units (SI).
