80 Fahrenheit to Celsius
80 degrees Fahrenheit equals
26.67°C
26.67 degrees Celsius
80°F is 26.67°C — warm, pleasant in dry air and noticeably hot once humidity climbs. Air conditioning is commonly set to hold rooms just under this range.
How to convert 80°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting 80°F
- 80 − 32 = 48
- 48 × 5/9 = 26.67
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 80°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 26.7°C (48°F) warmer |
| Room temperature | 21°C / 69.8°F | 5.7°C (10.2°F) warmer |
| Body temperature | 37°C / 98.6°F | 10.3°C (18.6°F) colder |
| Boiling point of water | 100°C / 212°F | 73.3°C (132°F) colder |
