MiB to MB Converter
Convert mebibytes to megabytes — 1,048,576 bytes against 1,000,000. Results update as you type; exact factors shown.
One mebibyte (2²⁰) is 1.0486 megabyte (10⁶) — see the exact factor, not a rounded rule of thumb.
How the mib to mb converter works
Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

FAQFrequently asked questions about data conversion
How many MB is 1 MiB?
1.048576 MB.
Where do I see MiB?
Linux tooling, RAM sizes and anything reporting true binary sizes.
Why is RAM always binary?
Because memory is addressed in powers of two, so a 16 GB module really is 16 GiB.
What is 1,024 MiB?
One gibibyte, which is 1.074 GB.
Is the difference growing?
Yes — 2.4% at kilo, 4.9% at mega, 7.4% at giga, 10% at tera.
