At what temperature are Celsius and Fahrenheit the same?

                          At what temperature are Celsius and Fahrenheit the same?

The formulas for converting between degree Celsius and degree Fahrenheit are -------

F = ( C * 9/5 ) +32 

C = ( F- 32 ) * 5/9

where F and C = Fahrenheit and Celsius reading

To find the temperature when both are equal , put F = C in one of the equations

C = ( C * 9/5 ) +32
C - ( C * 9/5 ) = 32
- 4/5 * C = 32
C =  -32 * 5/4
C = - 40

If we solve the other equation , we get the same value.

Conclusion  : So the temperature when both the Celsius and Fahrenheit scales are same is - 40 degrees.
