1 °C = 33.8 °F
The short answer
How many Fahrenheit is 1 Celsius?
1 °C = 33.8 °F. 1 Celsius = 1.800000 Fahrenheit, then + 32, so the working is 1 × 1.800000 + 32.0000 = 33.8.
The working
The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.
1 Celsius = 1.800000 Fahrenheit, then + 32 1 × 1.800000 + 32.0000 = 33.8
How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (°F) | Off by |
|---|---|---|
| Whole number | 34 | +0.20000 |
| 1 decimal | 33.8 | exact |
| 2 decimals | 33.80 | exact |
Round trip: take 33.8 °F back the other way and you land on 1.0000 °C — a drift of 0.0000 °C. That gap is the rounding, not the conversion.

Frequently asked questions
What is 1 Celsius in Fahrenheit?
1 Celsius is 33.8 Fahrenheit. 1 Celsius = 1.800000 Fahrenheit, then + 32, so the working is 1 × 1.800000 + 32.0000 = 33.8.
How accurate is 33.8 °F?
Rounding to 33.8 °F and converting straight back gives 1.0000 °C, a drift of 0.0000 °C from the 1 you started with. The factor itself is exact; every bit of that difference comes from the rounding, not the conversion.
