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 66 × 0.017453 = 1.1519
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 | −0.15192 |
| 1 decimal | 1.2 | +0.04808 |
| 2 decimals | 1.15 | −0.00192 |
Round trip: take 1.1519 rad back the other way and you land on 65.9990° — a drift of 0.0010°. That gap is the rounding, not the conversion.
