Difference between Petabyte and Zettabyte (PB vs ZB)

Petabyte (PB)

One Petabyte is equal to 10¹⁵ or 1000⁵ Bytes.
Petabyte is a decimal unit defined as per SI standard.
1 Petabyte = 1000 Terabytes.
The unit symbol for Petabyte is PB.
Petabyte is not same as Pebibyte (PiB) that contains 1024⁵ bytes.
1000 Petabytes = 1 Exabyte (EB).

Zettabyte (ZB)

One Zettabyte is equal to 10²¹ or 1000⁷ Bytes.
Zettabyte is a decimal unit defined as per SI standard.
1 Zettabyte = 1000 Exabytes.
The unit symbol for Zettabyte is ZB.
Zettabyte is not same as Zebibyte (ZiB) that contains 1024⁷ bytes.
1000 Zettabytes forms a Yottabyte (YB).

How to convert Petabyte to Zettabyte?

Below formula is used convert from Petabyte (PB) to Zettabyte (ZB) in the above PB to ZB Calculator.

PB to ZB Conversion Formula :

Zettabyte = Petabyte x (8x1000x1000x1000x1000x1000) / (8x1000x1000x1000x1000x1000x1000x1000)
or
Zettabyte = Petabyte x 0.000001

Petabyte to Zettabyte Conversion Steps : Petabyte is first converted to bits by multiplying with 8x1000x1000x1000x1000x1000 and then, converted to Zettabytes by dividing with 8x1000x1000x1000x1000x1000x1000x1000. In short, we can just multiply Petabyte with 0.000001 to get the value in Zettabyte.
