Not only are Celsius and Fahrenheit degrees different sizes (each Celsius degree covers more of the scale) they have different baselines. Fortunately, there are easier ways to convert temperatures ...

To convert from Fahrenheit to Celsius, simply subtract 32 and multiply by 0.5556 (or 5/9). Example: (75F - 32) x 0.5556 = 23.6C.

When converting Celsius to Fahrenheit, the formula is: (°C * 1.8) + 32 = °F. You multiply 1.8 to the number of degrees Celsius, then add that number to 32.
