12 Απρ 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 kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 × 10 −23 when expressed in the unit J K −1 , which is equal to kg m 2 s −2 K −1 , where the kilogram, metre and second are defined in terms of h , c and ∆ ν Cs ."
Learn about the SI unit of temperature, Kelvin, and how to convert it to other scales like Celsius and Fahrenheit. Find formulas, examples, and FAQs on temperature and heat units.
The kelvin (the unit name is spelled with a lower-case 'k') is the unit of temperature in the International System of Units (SI). The temperature of a body in a state of thermodynamic equilibrium is always positive relative to absolute zero.
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). The system can ...
