Frequently asked questions
What's the difference between GB and GiB?
Decimal units (KB, MB, GB) use powers of 1000; binary units (KiB, MiB, GiB) use powers of 1024. So 1 GB = 1000 MB, but 1 GiB = 1024 MiB. The tool handles both.
Why does my drive show less space than advertised?
Manufacturers usually advertise in decimal GB (1000-based), while operating systems often report in binary GiB (1024-based), so the reported size looks smaller. This converter lets you compare the two.
How many MB in a GB?
In decimal terms, 1 GB = 1000 MB. Select GB and MB to convert.
