How to convert 1 °C to °F
Use the formula °F = (°C × 9/5) + 32 and substitute 1 for °C:
°F = (1 × 9/5) + 32°F = 1.8 + 32°F = 33.8
So 1 °C = 33.8 °F.
What does 1 °C mean?
1 °C is cold. Outdoors it calls for a warm coat; it is also in the range of a refrigerator or a cool cellar.
- Fahrenheit
- 33.8 °F
- Kelvin
- 274.15 K
- Quick estimate (double + 30)
- 32 °F
For 1 °C the quick “double it and add 30” estimate gives 32 °F — 1.8 °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, 33.8 °F back to Celsius gives 1 °C.
