3 °C = 37.4 °F
The short answer
How many Fahrenheit is 3 Celsius?
3 °C = 37.4 °F. 1 Celsius = 1.800000 Fahrenheit, then + 32, so the working is 3 × 1.800000 + 32.0000 = 37.4.
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 3 × 1.800000 + 32.0000 = 37.4
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 | 37 | −0.40000 |
| 1 decimal | 37.4 | exact |
| 2 decimals | 37.40 | exact |
Round trip: take 37.4 °F back the other way and you land on 3.0000 °C — a drift of 0.0000 °C. That gap is the rounding, not the conversion.

Keep the refrigerator at 4 degrees Celsius, 40 Fahrenheit, or below, the FDA advises, to slow the bacteria that spoil food.
