-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
