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.

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 (rad) | Off by |
|---|---|---|
| Whole number | 1 | +0.45895 |
| 1 decimal | 0.5 | −0.04105 |
| 2 decimals | 0.54 | −0.00105 |
Round trip: take 0.5411 rad back the other way and you land on 31.0027° — a drift of 0.0027°. That gap is the rounding, not the conversion.
