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 225 × 0.017453 = 3.9270
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 | 4 | +0.07301 |
| 1 decimal | 3.9 | −0.02699 |
| 2 decimals | 3.93 | +0.00301 |
Round trip: take 3.9270 rad back the other way and you land on 225.0005° — a drift of 0.0005°. That gap is the rounding, not the conversion.
