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 = 0.000001 gigabytes 400,000 × 0.000001 = 0.400000
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 (GB) | Off by |
|---|---|---|
| Whole number | 0 | −0.40000 |
| 1 decimal | 0.4 | +0.00000 |
| 2 decimals | 0.40 | +0.00000 |
Round trip: take 0.400000 GB back the other way and you land on 400,000.0000 KB — a drift of 0.0000 KB. That gap is the rounding, not the conversion.
