How to Convert Fahrenheit to Celsius
To convert Fahrenheit (°F) to Celsius (°C), subtract 32 from the Fahrenheit value, then multiply by 5/9 (or divide by 1.8). Example: (68 °F − 32) × 5/9 = 20 °C. To convert Celsius to Fahrenheit, multiply by 9/5 and add 32: °F = °C × 9/5 + 32.
The United States uses Fahrenheit and most other countries — including the UK, Canada, EU, and Australia — use Celsius. This Fahrenheit to Celsius converter helps travelers, students, and cooks switch scales quickly.
