25 Fahrenheit to Celsius
25 °F ≈ -3.89 °C
25 degrees Fahrenheit is approximately -3.89 degrees Celsius.
How to convert 25 °F to °C
Use the formula °C = (°F − 32) × 5/9:
°C = (25 − 32) × 5/9°C = -7 × 5/9°C = -3.888889
So 25 °F = -3.888889 °C, or about -3.89 °C rounded.
Rounded values and quick estimate
- Rounded to a whole number: -4 °C
- Rounded to one decimal place: -3.9 °C
Quick mental estimate: subtract 30 and halve it. For 25 °F that gives about -2.5 °C — off by 1.39 °C (35.7%). Use the exact formula when precision matters.
