For the conversion from Fahrenheit to Celsius, you have to determine the formula
yourself. Don't forget the order of operations!"""
The formula for converting from Fahrenheit to Celsius is: C = (F - 32) / 1.8
This can be derived from the first formula:
F = C * 1.8 + 32 // now subtract 32 on both sides
F - 32 = C * 1.8 // then divide by 1.8
(F - 32) / 1.8 = C
