45 Fahrenheit to Celsius
45 degrees Fahrenheit equals
7.22°C
7.22 degrees Celsius
45°F is 7.22°C: cool enough for a jacket. A refrigerator interior sits in this range, as do early spring and late autumn days across much of the temperate world.
How to convert 45°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting 45°F
- 45 − 32 = 13
- 13 × 5/9 = 7.22
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 45°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 7.2°C (13°F) warmer |
| Room temperature | 21°C / 69.8°F | 13.8°C (24.8°F) colder |
| Body temperature | 37°C / 98.6°F | 29.8°C (53.6°F) colder |
| Boiling point of water | 100°C / 212°F | 92.8°C (167°F) colder |
