10 Fahrenheit to Celsius
10 °F ≈ -12.22 °C
10 degrees Fahrenheit is approximately -12.22 degrees Celsius.
How to convert 10 °F to °C
Use the formula °C = (°F − 32) × 5/9:
°C = (10 − 32) × 5/9°C = -22 × 5/9°C = -12.222222
So 10 °F = -12.222222 °C, or about -12.22 °C rounded.
Rounded values and quick estimate
- Rounded to a whole number: -12 °C
- Rounded to one decimal place: -12.2 °C
