-27 Fahrenheit to Celsius
-27 degrees Fahrenheit equals
-32.78°C
-32.78 degrees Celsius
-27°F is -32.78°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 -27°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting -27°F
- -27 − 32 = -59
- -59 × 5/9 = -32.78
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 -27°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 32.8°C (59°F) colder |
| Room temperature | 21°C / 69.8°F | 53.8°C (96.8°F) colder |
| Body temperature | 37°C / 98.6°F | 69.8°C (125.6°F) colder |
| Boiling point of water | 100°C / 212°F | 132.8°C (239°F) colder |
