The kelvin is the SI unit of thermodynamic temperature, defined by taking the fixed numerical value of the Boltzmann constant to be 1.380649×10−23 J K−1. The kelvin is part of the set of seven SI base units that form the foundation of modern science and technology.
12 kwi 2010 · Learn about the kelvin, the SI unit of temperature, and its relation to Celsius and Fahrenheit scales. Find resources for students and teachers on temperature measurement, conversion, and examples.
The basic unit of temperature in the International System of Units (SI) is the kelvin. It has the symbol K. For everyday applications, it is often convenient to use the Celsius scale, in which 0 °C corresponds very closely to the freezing point of water and 100 °C is its boiling point at sea level.
The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity).
