The petabyte (symbol PB) is 1015 bytes of digital information. A related unit, the pebibyte (PiB), using a binary prefix, is 10245 = 250 = 1125899906842624bytes, more than 12% larger.

1 PB = 1000000000000000B = 1015bytes = 1000terabytes.

The prefix peta indicates the fifth power of 1000 and means 1015 in the International System of Units (SI), and therefore 1 petabyte is one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes.

Usage examples[edit]

Examples of the use of the petabyte to describe data sizes in different fields are:
