Fahrenheit to Celsius Conversion Table
| Fahrenheit (°F) | Celsius (°C) | Description |
|---|---|---|
| -40°F | -40°C | Same on both scales |
| 0°F | -17.8°C | Very cold |
| 32°F | 0°C | Water freezes |
| 68°F | 20°C | Room temperature |
| 98.6°F | 37°C | Body temperature |
| 212°F | 100°C | Water boils |
How to Convert Fahrenheit to Celsius
The formula to convert Fahrenheit to Celsius is:
°C = (°F - 32) × 5/9
or: °C = (°F - 32) ÷ 1.8
Step-by-Step Example
Converting 77°F to Celsius:
- Subtract 32: 77 - 32 = 45
- Multiply by 5/9 (or divide by 1.8): 45 ÷ 1.8 = 25
- Result: 77°F = 25°C
Quick Mental Math Trick
For a rough estimate, subtract 30 and divide by 2. For example:
- 70°F: (70 - 30) ÷ 2 = 20°C (actual: 21.1°C)
- 90°F: (90 - 30) ÷ 2 = 30°C (actual: 32.2°C)
Common Use Cases
- Understanding US weather when traveling from metric countries
- Converting American oven temperatures for recipes
- Medical contexts (fever temperatures)
- HVAC and thermostat settings
- Scientific data conversion
Fun Fact
The only temperature that is the same in both Fahrenheit and Celsius is -40 degrees. At this point, -40°F = -40°C exactly!
