How do I convert gibibytes to mebibytes by hand?

Use MiB = GiB × 1,024. The step-by-step panel shows the same calculation with your own numbers substituted in.

Is the answer exact or rounded?

The calculation itself uses the full stored precision of the defined factor. Only the displayed figure is rounded, and the page also shows a shorter everyday value beside the full one.

Can I check the conversion the other way round?

Yes. The result panel converts the answer straight back into your original unit so you can confirm nothing was lost.

Can I download the result?

Yes — the PDF button produces a branded report with your input, the answer, the formula and the full working.

What this calculator does

Converts a measurement given in gibibyte (binary)s into mebibyte (binary)s using the defined conversion factor.

What your result means

The same quantity expressed in MiB instead of GiB. Nothing about the measurement itself changes.

Formula and working

MiB = GiB × 1,024

1
Start with your value
10 GiB
2
Convert to byte
10 × 1,073,741,824 = 10,737,418,000 B
3
Convert into mebibytes
10,737,418,000 ÷ 1,048,576 = 10,240 MiB
4
Result
10 GiB = 10,240 MiB

Frequently asked questions

Symbols and assumptions

GiB: Input unit — gibibyte (binary)
MiB: Output unit — mebibyte (binary)
B: Base unit used internally for digital storage

• Both units measure digital storage, so the physical quantity is unchanged by the conversion.
• The relationship is exactly linear: 1 GiB = 1,024 MiB.
• Values are converted through the SI base unit for this quantity rather than pair by pair.

• A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
• Displayed figures are rounded for readability; the full stored precision of the MiB value is used in every onward calculation.
