Celsius = Fahrenheit?

Classical Mechanics Level 1

In order to convert a Fahrenheit temperature F F to a Celsius temperature C , C, we use the following formula:

C = 5 9 ( F − 32 ) C = \frac{5}{9}(F - 32)

What is the numerical value at which both the Celsius and Fahrenheit scale indicate the same temperature?


The answer is -40.

F = ( 1.8 C ) + 32 F=(1.8C)+32
Here F = C F=C , So
F = ( 1.8 F ) + 32 F=(1.8F)+32
F − 1.8 F = 32 F-1.8F=32
F = − ( 32 / 0.8 ) F=-(32/0.8)
F = − 40 F=-40
− 4 0 ∘ C = − 4 0 ∘ F -40^\circ C = -40^\circ F
