(Given temperature - Lower fixed point)/Fundamental interval= Constant
Fundamental interval= Upper fixed point of the scale - Lower fixed point.
In the light of given general equation for the given question we can write
(F -32)/180= C/100
Plugging the given values you can get temperature either in Farhenheit or celcius scale as required.
Example 1 Convert 98.6° Fahrenheit (Normal Body Temperature!) to Celsius
First: 98.6° - 32 = 66.6 Then: 66.6× 5/9 = 333/9 = 37° C
