In short
How many bytes is 500 megabytes?
500 MB = 500,000,000 B. 1 megabyte = 1,000,000.000000 bytes, so the working is 500 × 1,000,000.000000 = 500,000,000.
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 megabyte = 1,000,000.000000 bytes 500 × 1,000,000.000000 = 500,000,000
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 (B) | Off by |
|---|---|---|
| Whole number | 500,000,000 | exact |
| 1 decimal | 500,000,000.0 | exact |
| 2 decimals | 500,000,000.00 | exact |
Round trip: take 500,000,000 B back the other way and you land on 500.0000 MB — a drift of 0.0000 MB. That gap is the rounding, not the conversion.
