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 kilobyte = 0.001000 megabytes 3,900 × 0.001000 = 3.9000
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.

|---|---|---|
| Whole number | 4 | +0.10000 |
| 1 decimal | 3.9 | exact |
| 2 decimals | 3.90 | exact |
Round trip: take 3.9000 MB back the other way and you land on 3,900.0000 KB — a drift of 0.0000 KB. That gap is the rounding, not the conversion.
