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 15 × 57.295780 = 859.44
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 | 859 | −0.43669 |
| 1 decimal | 859.4 | −0.03669 |
| 2 decimals | 859.44 | +0.00331 |
Round trip: take 859.44° back the other way and you land on 15.0001 rad — a drift of 0.0001 rad. That gap is the rounding, not the conversion.
