27 Fahrenheit to Celsius
27 °F ≈ -2.78 °C
27 degrees Fahrenheit is approximately -2.78 degrees Celsius.
How to convert 27 °F to °C
Use the formula °C = (°F − 32) × 5/9:
°C = (27 − 32) × 5/9°C = -5 × 5/9°C = -2.777778
So 27 °F = -2.777778 °C, or about -2.78 °C rounded.
Rounded values and quick estimate
- Rounded to a whole number: -3 °C
- Rounded to one decimal place: -2.8 °C
Quick mental estimate: subtract 30 and halve it. For 27 °F that gives about -1.5 °C — off by 1.28 °C (46%). Use the exact formula when precision matters.
