Convert Gigabytes to Petabytes (GB to PB)
1 gigabyte (GB) = 0.000001 petabytes (PB). 1 PB = 1000000 GB. Example: 15 GB = 15 × 0.000001 = 0.000015 PB.

How to Convert Gigabyte to Petabyte
- 1 GB = 0.000001 PB
- 1 PB = 1000000 GB
- Example: convert 15 GB to PB: 15 GB = 15 × 0.000001 PB = 0.000015 PB
Formula
PB = GB ÷ 1000000
Derivation from SI units:
- 1 GB = 10⁹ bytes = 8 × 10⁹ bits (decimal, SI).
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 GB = 8000000000 bit ÷ 8 × 10¹⁵ bit per PB = 0.000001 PB
Both units are defined exactly, so the factor is exact. Gigabyte definition: gigabyte; Petabyte definition: petabyte.
Worked examples
- A reading of 16 GB converts to 0.000016 PB.
16 GB × 0.000001 = 0.000016 PB - A value of 128 GB is 0.000128 PB.
128 GB × 0.000001 = 0.000128 PB
