Kelvin, base unit of thermodynamic temperature measurement in the International System of Units (SI). It is the fundamental unit of the Kelvin scale and has as its zero point absolute zero (−273.15 degrees on the Celsius temperature scale and −459.67 degrees on the Fahrenheit temperature scale).

The kelvin (symbol: K) is the base unit for temperature in the International System of Units (SI).
8 maj 2019 · The Kelvin temperature scale is an absolute temperature scale with zero at absolute zero. Because it is an absolute scale, measurements made using the Kelvin scale do not have degrees. The kelvin (note the lowercase letter) is the base unit of temperature in the International System of Units (SI).
The Kelvin scale is the temperature scale that is commonly used in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points ...
As part of a wider redefinition of the SI that came into effect in May 2019, the kelvin’s definition was changed, and is now expressed in terms of a fixed value of the Boltzmann constant, k. The official definition is as follows: “The kelvin, symbol K, is the SI unit of thermodynamic temperature.
15 maj 2018 · Instead, scientists measure its effect when it moves as heat (thermal energy in transit) to or from a system of objects. When heat no longer flows between these objects—in other words, when they are in thermal equilibrium—that is their thermodynamic temperature.
thermodynamic temperature: The kelvin, symbol K, is the SI base unit of thermodynamic temperature. 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 m 2 s −2 K −1, where the kilogram, metre and second are defined in ...
