Data Storage Converter

Every step on this page is a power of 1024. One gibibyte is 1024 mebibytes, and one kibibyte is 1024 bytes. The units are named B, KiB, MiB, GiB, and TiB.

When a label says MB or GB and means powers of 10, use the megabytes converter. That page has both decimal and binary rows.

Binary only

Bytes, kibibytes, mebibytes, gibibytes, and tebibytes. There is no decimal megabyte on this form. 1 TiB = 1024 GiB.

What the selects mean

Pick the unit you have and the unit you want. A value of 1 GiB to MiB is 1024. The result keeps up to six significant digits, so 1024 stays 1024.

Worked example: 1 GiB

From gibibytes to mebibytes, 1 GiB is 1024 MiB. From tebibytes to gibibytes, 1 TiB is 1024 GiB.

\[ 1\,\mathrm{GiB}=1024\,\mathrm{MiB} \]

Assumptions and limitations

Binary units only. Decimal MB and GB are on the megabytes page. Not a transfer-time tool.
