How the formula works
Fahrenheit = Celsius x 9 / 5 + 32. Celsius = (Fahrenheit - 32) x 5 / 9. The 32 offset is why temperature conversion is not a simple multiplier.
Useful reference points
Water freezes at 0 C or 32 F. A comfortable room is often around 20 C or 68 F. Water boils at about 100 C or 212 F at sea level.
Common mistake
Do not convert temperature like distance or weight. Because Fahrenheit and Celsius have different zero points, you need the full formula.
