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 18 × 57.295780 = 1,031.32
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 | 1,031 | −0.32403 |
| 1 decimal | 1,031.3 | −0.02403 |
| 2 decimals | 1,031.32 | −0.00403 |
Round trip: take 1,031.32° back the other way and you land on 17.9999 rad — a drift of 0.0001 rad. That gap is the rounding, not the conversion.
