Zettabyte (ZB)

Abbreviated as ZB, a zettabyte is equal to 1,180,591,620,717,411,303,424 (270) bytes or 1,000,000,000,000,000,000,000 (1021bytes.

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. The unit symbol is ZB.

1 ZB = 1000bytes = 1021 bytes = 1000000000000000000000 bytes = 1000 exabytes = 1 million petabytes = 1 billion terabytes = 1 trillion gigabytes.

A related unit, the zebibyte (ZiB), using a binary prefix, is equal to 1024bytes (approximately 1.181 ZB).
