-28 Celsius to Fahrenheit
-28 degrees Celsius equals
-18.4°F
-18.4 degrees Fahrenheit
-28°C is -18.4°F, well below the point where water freezes. Roads ice over here, and this is where winter forecasts in northern climates spend most of the season. For reference, water freezes at 0°C, or 32°F.
How to convert -28°C to °F
Formula
°F = °C × 9/5 + 32
Substituting -28°C
- -28 × 9/5 = -50.4
- -50.4 + 32 = -18.4
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 -28°C compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 28°C (50.4°F) colder |
| Room temperature | 21°C / 69.8°F | 49°C (88.2°F) colder |
| Body temperature | 37°C / 98.6°F | 65°C (117°F) colder |
| Boiling point of water | 100°C / 212°F | 128°C (230.4°F) colder |
