皆位元組(英語:Zettabyte,縮寫為ZB)(又稱十垓位元組),是資訊計量單位位元組的多倍形式。國際單位制(SI)以1021來定義字首澤它,故1皆位元組表示1021位元組[1]。

Zebibyte(縮寫:ZiB)是另一個類似的單位,使用二進位字首,表示1,180,591,620,717,411,303,424(270)位元組,常與皆位元組混淆。
2016年,全世界網際網路流量超過1 ZB,開啟了皆位元組時代。[2]
- 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,皆位元組往往亦可以指Zebibyte,其換算公式是:
- 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
