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 radian = 57.295780 degrees 4 × 57.295780 = 229.18
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 (°) | Off by |
|---|---|---|
| Whole number | 229 | −0.18312 |
| 1 decimal | 229.2 | +0.01688 |
| 2 decimals | 229.18 | −0.00312 |
Round trip: take 229.18° back the other way and you land on 3.9999 rad — a drift of 0.0001 rad. That gap is the rounding, not the conversion.
