How to convert Fahrenheit to Celsius
Temperature scales have different zero points, so you can't just multiply: there's an offset too.
°C = (°F − 32) × 5/9
Example: 350 °F = 176.67 °C. Water freezes at 32 °F and boils at 212 °F.
About the degree Fahrenheit and the degree Celsius
Degree Fahrenheit (°F)
Daniel Gabriel Fahrenheit proposed his scale in 1724. Water freezes at 32 °F and boils at 212 °F. The US is the main country that still uses it day to day.
Degree Celsius (°C)
The Celsius scale (also called centigrade) puts the freezing point of water at 0 °C and its boiling point at 100 °C at sea-level pressure. Formally it is defined from the kelvin: °C = K − 273.15.
