What is the relation between Celsius and Fahrenheit?

Hint: Both are temperature measuring parameters with different scale values, same temperature can be measured by both the Celsius as well as Fahrenheit scale. The temperature scales are used to measure temperatures and find wide use in doctor’s clinics, laboratories and industrial purposes. There are scales called absolute scales in which the initial point starts from zero and it moves only in one direction.

Complete answer:
Celsius (C) scale to its Fahrenheit (F) relation is: $\dfrac{F-32}{9}=\dfrac{C}{5}$ . Celsius temperature scale also called centigrade temperature scale, is the scale based on 0 for the freezing point of water and 100 for the boiling point of water. The lowest temperature that can be recorded in Celsius scale is -273.15 \[{}^\circ C\].The Fahrenheit scale is most widely used to measure the temperature of the human body. Similarly, the Celsius scale is used in laboratories while doing experiments and all.

Note:There are basically three temperature scales in use namely Celsius, Fahrenheit & Kelvin.The lower point or the ice point of Celsius scale is ${{0}^{0}}C$ & it's upper or the steam point is ${{100}^{0}}C$. It has thus 100 divisions in its scale.The lower point or ice point of Fahrenheit scale is ${{32}^{0}}F$ & it's upper or the steam point is ${{212}^{0}}F$. It has thus 180 divisions in its scale.In The third scale, the Kelvin scale ice point is 273 K and Steam point is 373 K. It has thus 100 divisions.
