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 degree = 0.017453 radians 28 × 0.017453 = 0.4887
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 | 0 | −0.48869 |
| 1 decimal | 0.5 | +0.01131 |
| 2 decimals | 0.49 | +0.00131 |
Round trip: take 0.4887 rad back the other way and you land on 28.0004° — a drift of 0.0004°. That gap is the rounding, not the conversion.
