-15 Fahrenheit to Celsius
-15 degrees Fahrenheit equals
-26.11°C
-26.11 degrees Celsius
-15°F is -26.11°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 -15°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting -15°F
- -15 − 32 = -47
- -47 × 5/9 = -26.11
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 -15°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 26.1°C (47°F) colder |
| Room temperature | 21°C / 69.8°F | 47.1°C (84.8°F) colder |
| Body temperature | 37°C / 98.6°F | 63.1°C (113.6°F) colder |
| Boiling point of water | 100°C / 212°F | 126.1°C (227°F) colder |
