A pebibyte (a contraction of peta binary byte) is a unit of information or computer storage, abbreviated PiB.

1 pebibyte = 2⁵⁰ bytes = 1,125,899,906,842,624 bytes = 1,024 tebibytes

The pebibyte is closely related to the petabyte, which can either be used as a popular synonym for pebibyte, or to refer to 10¹⁵ bytes = 1,000,000,000,000,000 bytes, depending on context (see binary prefix).
