Understanding your result
The converted value describes the same data quantity in the selected target unit. Display rounding does not add precision to the original measurement.
Common mistakes
- Confusing the source and target units, or overlooking a prefix or case-sensitive symbol.
- Mixing bits and bytes, or decimal kB/MB with binary KiB/MiB.

- Compare storage capacities using decimal or binary prefixes.
- Translate between bits and bytes.
How it works
For the displayed direction, 1 GB equals 1000 MB. The engine converts through the shared data base quantity. Decimal prefixes use powers of 1,000; binary prefixes use powers of 1,024. One byte is eight bits. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits.
