To convert Celsius into Fahrenheit, which equation is correct?
A. 5/9 3 °C 2 32
B. 1.8 3 °C 1 32
C. 1.8 3 °C 2 32
D. 5/9 3 °C 1 32
b
Rationale: Because Celsius degrees are 1.8 times greater than Fahrenheit degrees, it is easy to understand that you must multiply a given Celsius temperature by 1.8 and then add 32 to the result because of the differential in calculating tempera-tures on these scales. For further understanding, whereas the Fahrenheit scale ranges from 32 to 212 degrees between its freezing and boiling points, the Celsius scale only ranges from 0 to 100 degrees between its equivalent points.
