-25 Fahrenheit to Celsius
-25 degrees Fahrenheit equals
-31.67°C
-31.67 degrees Celsius
-25°F is -31.67°C — deep-freeze territory, colder than a household freezer and cold enough to risk frostbite on exposed skin within minutes. -40°C is the single point where both scales agree, reading -40°F as well.
How to convert -25°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting -25°F
- -25 − 32 = -57
- -57 × 5/9 = -31.67
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 -25°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 31.7°C (57°F) colder |
| Room temperature | 21°C / 69.8°F | 52.7°C (94.8°F) colder |
| Body temperature | 37°C / 98.6°F | 68.7°C (123.6°F) colder |
| Boiling point of water | 100°C / 212°F | 131.7°C (237°F) colder |
