-25 Fahrenheit to Celsius
-25 °F ≈ -31.67 °C
-25 degrees Fahrenheit is approximately -31.67 degrees Celsius.
How to convert -25 °F to °C
Use the formula °C = (°F − 32) × 5/9:
°C = (-25 − 32) × 5/9°C = -57 × 5/9°C = -31.666667
So -25 °F = -31.666667 °C, or about -31.67 °C rounded.
Rounded values and quick estimate
- Rounded to a whole number: -32 °C
- Rounded to one decimal place: -31.7 °C
