Question

Why are different scales of temperature used?

Answer 1

They have different uses for differnt people

Explanation:

The Celsius scale is based on two improtant properties of one of the most common compounds on earth: the freezing and point of water, designated `0^oCand100^oC` respectively.

The Fahrenheit scale is based on an experiment to make a freezing solution (`0^oF`) and the average body temperature of Mrs. Fahrenheit (`100^oF`). Only Americans still use it, as far as I know.

The Kelvin scale is based on the lowest possible temperature, the so-called absolute zero. The distance between degree marks is the same as in the Celsius scale. `0K~~-273.15^oC`).

The Celsius scale is used for everyday life. Using the Kelvin scale in chemistry and physics makes us avoid a lot of awkwardness in calculations.
