∙ 14y agoTake one of the formulas you use to convert one to the other.
Let's say, take the formula used to convert °C to °F :
F = 1.8 C + 32.
Since we want the °F and °C numbers to be equal, we can replace
the 'F' on the left side with 'C':
C = 1.8 C + 32
Subtract 32 from each side:
C - 32 = 1.8 C
Subtract C from each side:
-32 = 0.8 C
Divide each side by 0.8 :
-32/0.8 = C = -40
That's the number to remember:
-40°F = -40°C

∙ 14y agoTo convert Fahrenheit to Celsius, you can use the formula: (Fahrenheit - 32) * 5/9 = Celsius. To find when Fahrenheit equals Celsius, you set the two values equal to each other and solve for the variable.

T (0F) = 32+1.8 *T(0C)
T(0F)=T(0C)=X
X=32+1.8*X
-0.8X=32
X=32/-0.8
X=-40
