Question

Why is kelvin considered as the best scale of measuring the temperature?​

Answer 1

Kelvin is the best scale for measuring the temperature because it has no maximum temperature and it can measure temperature to any extent.

Answer 2

${\sf{\color{lime}{Answer:-}}}$

Kelvin scale is an absolute zero temperature scale and the minimum temperature that it can have is 0K. Thus Kelvin scale does not give any negative values. This makes Kelvin scale to be convenient for use. Because it is an absolute scale, measurements made using the Kelvin scale do not have degrees.
