The CGPM designated 273.15 K as a reference point for the triple point of water. It was when the General Conference on Weights and Measures (CGPM) adopted the Kelvin (K) as the base unit for thermodynamic temperature and made decisions about the measurement standards. Scientists have used Kelvin as the preferred scale of measurement since 1954. He cultivated the concept of absolute temperature, today known as the “Second Law of Thermodynamics”, and created the dynamical theory of heat. Kelvin's Origin / Historyīritish physicist William Lord Kelvin invented the Kelvin scale in 1848. 0 K is regarded as an absolute zero, and pure water boils to 373.15 K and freezes precisely to 273.15 K at standard atmospheric pressure. The Kelvin scale is defined by fixing the numeral value of the Boltzmann Constant K to 1.380649×10−23 J ⋅ K−1. Its increments still closely resemble the historic definition of a degree Celsius. The unit was created by shifting the initial point of the Celsius scale down from the water’s melting point to absolute zero. The Kelvin scale is an absolute thermodynamic temperature scale, which means that the unit uses absolute zero as its null point. Its increment still very much resembles the ancient definition of a degree celsius. The unit was formulated by shifting the initial point of the Celsius scale down from the melting point of water to absolute zero. The Kelvin scale is an absolute thermodynamic temperature scale which implies that the unit employs absolute zero as its null point. Nonetheless, Celsius still dominates this scale and is used to measure temperature in most countries. Kelvin is the primary unit of measuring temperature in physical sciences.
