1ZB= 1trillion gigabytes

In Bytes 1 Zettabyte (ZB) = 1,000,000,000,000,000,000,000 bytes = 10²¹ bytes and In Gigabytes 1 ZB = 1,000,000,000,000 GB = 1 trillion GB In bytes (21 zeros) In gigabytes (12 zeros)

Trilliongegabytes= 1ZB

2^30 GB = 1ZB

1000000000000 gigabytes in 1 zettabyte

One zettabyte is equal to one sextillion bytes or 1021 (1,000,000,000,000,000,000,000) bytes, or, one zettabyte is equal to a trillion gigabytes.

1 zettabyte = 10^12gigabyte

1 zeta byte =1000000000000 gb
