Question

why is Kelvin is considered as the SI unit of temperature? why we are not taking the Celsius scale as SI unit?​

Answer 1

Answer:

Kelvin is taken as the SI unit of temperature because it fulfils Thomson's requirements as an absolute thermodynamic temperature scale. In 1848, Kelvin used this as the basis for an absolute temperature scale, where "absolute" means that at this temperature, molecules would stop moving. From absolute zero, he used the same unit as Celsius to determine the increments.
