WebMar 20, 2024 · kelvin (K), base unit of thermodynamic temperature measurement in the International System of Units (SI). The 2024 General Conference on Weights and Measures decided that effective from May 20, 2024, the unit would be defined such that the Boltzmann constant would be equal to 1.380649 × 10 −23 joule per kelvin. WebTHE SI The SI — the modern metric system — has seven base units from which all other measurement units can be derived. On May 20, 2024, four of them — the kilogram, kelvin, ampere and mole — were redefined in terms of constants of nature. The remaining three — the second, meter, and candela — are already based on universal constants.
