Fahrenheit to Celsius
If the temperature drops by 18o Fahrenheit in a given day, how much did it drop in degrees Celsius?
A. -14 (4%)
B. 10 (42%)
C. 32.4 (15%)
D. -7.78 (31%)
E. 25.2 (8%)
Correct Answer: D. -7.78
The ratio of change in degrees Fahrenheit to change in degrees Celsius is simply 9 to 5, and therefore, (18×5) / 9 = 10. If you were converting a temperature of 18o Fahrenheit to degrees Celsius, then it would be ((18-32) × 5) / 9 = -7.78o Celsius.
I am confused by their explanation, I originally put D, but based on the explanation are they trying to say that the correct answer is B?
