-10 Fahrenheit to Celsius
-10 degrees Fahrenheit equals
-23.33°C
-23.33 degrees Celsius
-10°F is -23.33°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 -10°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting -10°F
- -10 − 32 = -42
- -42 × 5/9 = -23.33
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 -10°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 23.3°C (42°F) colder |
| Room temperature | 21°C / 69.8°F | 44.3°C (79.8°F) colder |
| Body temperature | 37°C / 98.6°F | 60.3°C (108.6°F) colder |
| Boiling point of water | 100°C / 212°F | 123.3°C (222°F) colder |
