The same number, -40 C.

F = 9/5 C + 32

C = 5/9 (F -32), F is -40

C = 5/9 (-40 -32)

C = 5/9 (- 72)

C = - (5 x 72) / 9

C = - 360 / 9

C = -40

In your head: "twice C minus 10% plus 32 is F"

2 x -40 C = -80; -80 - (-8) = -72; -72 +32 = -40 F

Similarly, 2x100C-20+32= 212F, boiling point of pure water at STP

Use this formula to convert from Celsius to Fahrenheit:


F=1.8C+32

Use this formula to convert from Fahrenheit to Celsius:

C=(5/9)(F-32)

-40*F=-40*C. This is the only place on the thermometer where the two number values of degrees are the same and the temperatures are equal.
