1,000,000,000 B = 1,000.000000 MB

In short

How many megabytes is 1,000,000,000 bytes?

1,000,000,000 B = 1,000.000000 MB. 1 byte = 0.000001 megabytes, so the working is 1,000,000,000 × 0.000001 = 1,000.000000.

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 byte = 0.000001 megabytes
1,000,000,000 × 0.000001 = 1,000.000000

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.

Round trip: take 1,000.000000 MB back the other way and you land on 1,000,000,000.0000 B — a drift of 0.0000 B. That gap is the rounding, not the conversion.
