About Fahrenheit to Celsius Conversion
Converting Fahrenheit to Celsius is essential for international communication, scientific work, and understanding weather reports when traveling from the United States to countries that use the metric system.
Conversion Formula
°C = (°F - 32) × 5/9
Example: 68°F = (68 - 32) × 5/9 = 36 × 5/9 = 20°C
Quick Reference Table
| Fahrenheit (°F) | Celsius (°C) |
|---|---|
| -40°F | -40°C |
| -4°F | -20°C |
| 32°F | 0°C |
| 50°F | 10°C |
| 68°F | 20°C |
| 86°F | 30°C |
| 98.6°F | 37°C |
| 212°F | 100°C |
Common Uses
- • International Travel: Understanding weather when visiting metric countries
