Why kelvin considered as the best scale for measuring temperature?

Kelvin is considered the best scale for measuring temperature because it is an absolute scale that starts at absolute zero, the theoretical point where all molecular movement ceases. This means that temperatures measured in kelvin are directly proportional to the average kinetic energy of the particles in a substance, providing a more accurate and consistent measurement compared to other scales. Additionally, the Kelvin scale does not have any negative values, making it easier for calculations and comparisons in scientific research and engineering.
