30 Fahrenheit to Celsius
30 degrees Fahrenheit equals
-1.11°C
-1.11 degrees Celsius
30°F works out to -1.11°C, right around the freezing point of water — 0°C or 32°F. This is typical winter weather in temperate regions and the band most refrigerators hold.
How to convert 30°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting 30°F
- 30 − 32 = -2
- -2 × 5/9 = -1.11
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 30°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 1.1°C (2°F) colder |
| Room temperature | 21°C / 69.8°F | 22.1°C (39.8°F) colder |
| Body temperature | 37°C / 98.6°F | 38.1°C (68.6°F) colder |
| Boiling point of water | 100°C / 212°F | 101.1°C (182°F) colder |
