How to convert -4 °C to °F
Use the formula °F = (°C × 9/5) + 32 and substitute -4 for °C:
°F = (-4 × 9/5) + 32°F = -7.2 + 32°F = 24.8
So -4 °C = 24.8 °F.
What does -4 °C mean?
-4 °C is below the freezing point of water (0 °C / 32 °F), so expect ice and frost. In weather terms it is a cold winter day.

- Quick estimate (double + 30)
- 22 °F
For -4 °C the quick “double it and add 30” estimate gives 22 °F — 2.8 °F too low. The shortcut works best between about 0 °C and 20 °C; use the exact formula for anything that matters.

The Celsius to Fahrenheit formula
°F = (°C × 9/5) + 32
Multiply the Celsius temperature by 9/5 (1.8) because a Celsius degree is 1.8 times larger than a Fahrenheit degree, then add 32 because water freezes at 32 °F rather than 0 °F. To go the other way, use °C = (°F − 32) × 5/9 — for example, 24.8 °F back to Celsius gives -4 °C.
