kelvin on määratud Boltzmanni konstandi k fikseerimisega väärtusarvul 1,380 649 × 10–34 väljendatuna ühiku J K–1abil, mis on võrdne kg m2 s–2 K–1, kus kilogramm on määratletud h, meeter c ja sekund ∆νCs alusel
Good to know
Kelvin (tähis K) on SI termodünaamilise temperatuuri ühik ja ühtlasi on ka SI põhiühik.
the kelvin 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 m2 s–2 K–1, where the kilogram, metre and second are defined in terms of h, c and ∆νCs
Good to know
The kelvin, symbol K, is the SI unit of thermodynamic temperature and is the base unit of the SI.
