23 Fahrenheit to Celsius
23 °F = -5 °C
23 degrees Fahrenheit equals -5 degrees Celsius.
How to convert 23 °F to °C
Use the formula °C = (°F − 32) × 5/9:
°C = (23 − 32) × 5/9°C = -9 × 5/9°C = -5
So 23 °F = -5 °C.
Rounded values and quick estimate
- Rounded to a whole number: -5 °C
- Rounded to one decimal place: -5 °C
Quick mental estimate: subtract 30 and halve it. For 23 °F that gives about -3.5 °C — off by 1.5 °C (30%). Use the exact formula when precision matters.
