-40 degrees C in Fahrenheit is
- -72 degrees F.
- -8 degrees F.
- -40 degrees F.
Explanation from PART66Online
Using degreesF = (9/5 * degreesC) + 32: (9/5 * -40) + 32 = -72 + 32 = -40 degreesF. Minus forty is the unique point where the Celsius and Fahrenheit scales read the same value, which is why this conversion is a classic check.

T(°C) = (T(°F) - 32) × 5/9

why?I think it is wrong,the formula i know is F=9/5*C+32 the answer if i place -40 instead of C is 72+32=104 i think this answer is wrong .When we know F and we search for C the formula is 5/9*(F-32) .So i think dimky used the wrong formula.Or i am confused.

the formula is T(F)= (t(°C)*9/5)+32
