How to convert Fahrenheit to Celsius
To convert Fahrenheit to Celsius, use this formula:
°C = (°F − 32) × 5/9
Example: (100 °F − 32) × 5/9 = 37.7778 °C
Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level, and the two scales show the same number at −40 degrees. Fahrenheit is used mainly in the United States; most other countries use Celsius.
