The short answer

4,000 MB = 4.000 GB, which reads as 4 GB. 1 megabyte = 0.001000 gigabytes, so the working is 4,000 × 0.001000 = 4.000.
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 megabyte = 0.001000 gigabytes 4,000 × 0.001000 = 4.000
4,000 megabytes as 4 GB
A decimal is the right form for a spreadsheet and the wrong one for almost everything else. Split into whole units, 4,000 MB is 4 GB — the reading you would actually give someone, and the one a tape measure, a scale, or a timetable is marked in.
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 | 4 | exact |
| 1 decimal | 4.0 | exact |
| 2 decimals | 4.00 | exact |
Round trip: take 4.000 GB back the other way and you land on 4,000.0000 MB — a drift of 0.0000 MB. That gap is the rounding, not the conversion.
