Fahrenheit to Celsius formula
°C = ((°F+459.67)*5/9)-273.15
Temperature scales differ in both their zero point and their degree size, so a conversion needs a multiplication and an offset — unlike length or weight, where a single factor is enough.

About Fahrenheit
The Fahrenheit scale puts water’s freezing point at 32° and its boiling point at 212°, and is used mainly in the United States.
About Celsius
The Celsius scale puts the freezing point of water at 0° and its boiling point at 100° at standard pressure.
