Convert Petabytes to Gigabytes (PB to GB)
1 petabyte (PB) = 1000000 gigabytes (GB). 1 GB = 0.000001 PB. Example: 15 PB = 15 × 1000000 = 15000000 GB.
Also searched as petabytes to GB, petabytes in GB, petabytes into gigabytes, PB to GB, PB in gigabytes, PB into gigabyte, petabyte to gigabyte, PB to gigabytes converter and how many gigabytes in a petabyte.

How to Convert Petabyte to Gigabyte
- 1 PB = 1000000 GB
- 1 GB = 0.000001 PB
- Example: convert 15 PB to GB: 15 PB = 15 × 1000000 GB = 15000000 GB
Formula
GB = PB × 1000000
Derivation from SI units:
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 GB = 10⁹ bytes = 8 × 10⁹ bits (decimal, SI).
- 1 PB = 8 × 10¹⁵ bit ÷ 8000000000 bit per GB = 1000000 GB
Both units are defined exactly, so the factor is exact. Petabyte definition: petabyte; Gigabyte definition: gigabyte.
Worked examples
- A reading of 1 PB converts to 1000000 GB.
1 PB × 1000000 = 1000000 GB - A value of 10 PB is 10000000 GB.
10 PB × 1000000 = 10000000 GB
