To convert Celsius into Fahrenheit, which equation is correct?

A) 5/9 × °C - 32
B) 1.8 × °C + 32
C) 1.8 × °C - 32
D) 5/9 × °C + 32

B) 1.8 × °C + 32
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 temperatures 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.
