Mebibytes to Megabytes
A mebibyte is 1,024 kibibytes (1,048,576 bytes), the binary unit your OS may show when it says "MB" for RAM or files. A megabyte is 1,000 kilobytes, a common unit for document, photo, and small app file sizes. 1 MiB equals ≈1.04858 MB, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to data, measured here against data's base unit (bit) — every other data unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
MB = MiB × ≈1.04858
MiB = MB × ≈0.953674
Worked example: 5 MiB × ≈1.04858 = 5.24288 MB.
