Zettabyte

Zettabyte（ZB,澤它位元組或皆位元組），是一種資訊計量單位，現今通常在標示網路硬碟總容量，或具有大容量的儲存媒介之儲存容量時使用。

1ZB = 1,000 EB

1ZB = 1,000,000 (10)PB

1ZB = 1,000,000,000 (10)TB

1ZB = 1,000,000,000,000 (10)GB

1ZB = 1,000,000,000,000,000 (10)MB

1ZB = 1,000,000,000,000,000,000 (10)KB

1ZB = 1,000,000,000,000,000,000,000 (10)B

另外，Zettabyte往往亦可以指Zebibyte，其換算公式是：

1ZiB = 1,024 EiB

1ZiB = 1,048,576 (1024)PiB

1ZiB = 1,073,741,824 (1024)TiB

1ZiB = 1,099,511,627,776 (1024)GiB

1ZiB = 1,125,899,906,842,624 (1024)MiB

1ZiB = 1,152,921,504,606,846,976 (1024)KiB

1ZiB = 1,180,591,620,717,411,303,424 (1024)B
