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 ${0}^{o} C \mathmr{and} {100}^{o} C$ respectively.

The Fahrenheit scale is based on an experiment to make a freezing solution (${0}^{o} F$) and the average body temperature of Mrs. Fahrenheit (${100}^{o} F$). 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. $0 K \approx - {273.15}^{o} C$).

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.
