How is the kelvin defined
WebThe kelvin (K) is therefore regarded as a unit of temperature, much as a metre is regarded as a unit of length, or a kilogram as a unit of mass. One therefore does not talk about a temperature of so many "degrees Kelvin", any more than one would talk about a length of so many "degrees metre" or a mass of so many "degrees kilogram".

WebThe Kelvin scale is a unit of temperature, mostly used in the world of science. The scale was invented by Lord Kelvin who saw the need for a scale where absolute zero was the null point, which means that 0 K is the lowest possible temperature = -273,15 °C. The Kelvin Scale uses Celsius for its unit increment, meaning that +1 K is the same as ...
