-40 degrees Fahrenheit is equal to how many degrees on the Celsius scale?
- A+ 40
- B– 32
- C– 40
- D0
Solution & Step-by-step Explanation
To convert Fahrenheit (F) to Celsius (C), we use the formula:
C=
9
5
(F−32)
Substituting F=−40:
C=
9
5
(−40−32)
C=
9
5
(−72)
C=5×(−8)=−40
Thus, −40
∘
F is exactly equal to −40
∘
C. This is the unique temperature at which both scales intersect.
