How to Convert Fahrenheit to Celsius
The Fahrenheit to Celsius conversion formula is straightforward. First subtract 32 from the Fahrenheit value, then multiply by 5/9. This works for weather, body temperature, oven settings, and scientific reference values.
Step-by-step example: Convert 104.8°F to Celsius
- Subtract 32: 104.8 − 32 = 72.8
- Multiply by 5/9: 72.8 × 5/9 = 40.4
- Result: 104.8°F = 40.4°C
This example is important because 104.8°F isn't just a number—it's a dangerous fever temperature. If you or someone you care about has a fever this high, get medical help right away.
