-11 Fahrenheit to Celsius
-11 degrees Fahrenheit equals
-23.89°C
-23.89 degrees Celsius
-11°F is -23.89°C, well below the point where water freezes. Roads ice over here, and this is where winter forecasts in northern climates spend most of the season. For reference, water freezes at 0°C, or 32°F.
How to convert -11°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting -11°F
- -11 − 32 = -43
- -43 × 5/9 = -23.89
Fahrenheit places the freezing point of water at 32 rather than 0, so that offset comes off first. What remains is then scaled by 5/9, because a Celsius degree covers 1.8 times as much temperature change as a Fahrenheit degree.
How -11°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 23.9°C (43°F) colder |
| Room temperature | 21°C / 69.8°F | 44.9°C (80.8°F) colder |
| Body temperature | 37°C / 98.6°F | 60.9°C (109.6°F) colder |
| Boiling point of water | 100°C / 212°F | 123.9°C (223°F) colder |
