77 Fahrenheit to Celsius
77 degrees Fahrenheit equals
25°C
25 degrees Celsius
77°F is 25°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 77°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting 77°F
- 77 − 32 = 45
- 45 × 5/9 = 25
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 77°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 25°C (45°F) warmer |
| Room temperature | 21°C / 69.8°F | 4°C (7.2°F) warmer |
| Body temperature | 37°C / 98.6°F | 12°C (21.6°F) colder |
| Boiling point of water | 100°C / 212°F | 75°C (135°F) colder |
