How to convert degrees Fahrenheit to degrees Celsius
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or divide by 1.8).
Formula
°C = (°F − 32) × 5/9
Examples
- 68 °F → (68 − 32) ÷ 1.8 = 20 °C
- 98.6 °F → (98.6 − 32) ÷ 1.8 = 37 °C
- 350 °F → (350 − 32) ÷ 1.8 = 176.6667 °C

About degrees Fahrenheit
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so one Fahrenheit degree is 5/9 of a Celsius degree. It is the everyday scale in the United States for weather, ovens and body temperature.
About degrees Celsius
On the Celsius scale water freezes at 0 °C and boils at about 100 °C at sea-level pressure. Today it is formally defined from the kelvin (°C = K − 273.15). It is the scale used for weather and cooking in almost every country.
