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 9 × 57.295780 = 515.66
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 | 516 | +0.33798 |
| 1 decimal | 515.7 | +0.03798 |
| 2 decimals | 515.66 | −0.00202 |
Round trip: take 515.66° back the other way and you land on 9.0000 rad — a drift of 0.0000 rad. That gap is the rounding, not the conversion.
