Data size converter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

How to convert data size

Decimal prefixes use powers of 1000; binary prefixes use powers of 1024. Lowercase b means bits, uppercase B means bytes. This is an amount, not transfer speed.

Multiply by the source unit factor to get the base quantity, then divide by the target factor. The other-units table compares the same value without retyping it.

A worked example

1 GB = 1000000000 bytes; divided by 1048576 gives about 953.6743164 MiB.

Before you use the result

Displayed values are rounded; extra digits do not make your measurement more accurate. Decimal prefixes use powers of 1000; binary prefixes use powers of 1024. Lowercase b means bits, uppercase B means bytes. This is an amount, not transfer speed.

GB (decimal) to MiB (binary): reference values

GB (decimal)	MiB (binary)
1	953.6743164
10	9536.743164
100	95367.43164

Calculated with the same conversion as the tool above.
