The zettabyte is a multiple of the unit byte for digital information. The prefix zetta indicates multiplication by the seventh power of 1000 or 1021 in the International System of Units (SI). A zettabyte is one sextillion (one long scale trilliard) bytes.[1][2][3][4][5] The unit symbol is ZB.

1 ZB = 10007bytes = 1021bytes = 1000000000000000000000bytes = 1000exabytes = 1millionpetabytes = 1billionterabytes = 1trilliongigabytes.

A related unit, the zebibyte (ZiB), using a binary prefix, is equal to 10247bytes.
