泽字节

英語:,縮寫為ZB)(又稱十垓位元組),是信息计量单位字节的多倍形式。国际单位制(SI)以1021来定义前缀泽它,故1泽字节表示1021字节[1]

Zebibyte(缩写:ZiB)是另一个类似的單位,使用二进制前缀,表示1,180,591,620,717,411,303,424(270)字节,常与泽字节混淆。

2016年,全世界互联网流量超过1 ZB,开启了泽字节时代[2]

與其他儲存單位的換算

  • 1 ZB = 1,000 EB
  • 1 ZB = 1,000,000 (106) PB
  • 1 ZB = 1,000,000,000 (109) TB
  • 1 ZB = 1,000,000,000,000 (1012) GB
  • 1 ZB = 1,000,000,000,000,000 (1015) MB
  • 1 ZB = 1,000,000,000,000,000,000 (1018) KB
  • 1 ZB = 1,000,000,000,000,000,000,000 (1021) B

另外,泽字节往往亦可以指Zebibyte,其换算公式是:

  • 1 ZB ≈ 0.847 ZiB
  • 1 ZiB = 1,024 EiB
  • 1 ZiB = 1,048,576 (10242) PiB
  • 1 ZiB = 1,073,741,824 (10243) TiB
  • 1 ZiB = 1,099,511,627,776 (10244) GiB
  • 1 ZiB = 1,125,899,906,842,624 (10245) MiB
  • 1 ZiB = 1,152,921,504,606,846,976 (10246) KiB
  • 1 ZiB = 1,180,591,620,717,411,303,424 (10247) B
