-1 Celsius to Fahrenheit
-1 degrees Celsius equals
30.2°F
30.2 degrees Fahrenheit
-1°C works out to 30.2°F, 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 -1°C to °F
Formula
°F = °C × 9/5 + 32
Substituting -1°C
- -1 × 9/5 = -1.8
- -1.8 + 32 = 30.2
The two scales differ in both their zero point and their step size. A Fahrenheit degree is 5/9 the size of a Celsius degree, and the scales are offset by 32 degrees at the freezing point of water — which is why the conversion needs both a multiplication and an addition.
How -1°C compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 1°C (1.8°F) colder |
| Room temperature | 21°C / 69.8°F | 22°C (39.6°F) colder |
| Body temperature | 37°C / 98.6°F | 38°C (68.4°F) colder |
| Boiling point of water | 100°C / 212°F | 101°C (181.8°F) colder |
