1,000 GB = 1,000,000 MB
The short answer
How many megabytes is 1,000 gigabytes?
1,000 GB = 1,000,000 MB. 1 gigabyte = 1,000.000000 megabytes, so the working is 1,000 × 1,000.000000 = 1,000,000.
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 gigabyte = 1,000.000000 megabytes 1,000 × 1,000.000000 = 1,000,000
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 (MB) | Off by |
|---|---|---|
| Whole number | 1,000,000 | exact |
| 1 decimal | 1,000,000.0 | exact |
| 2 decimals | 1,000,000.00 | exact |
Round trip: take 1,000,000 MB back the other way and you land on 1,000.0000 GB — a drift of 0.0000 GB. That gap is the rounding, not the conversion.
