How do I convert petabytes back to gigabytes?

Use the reverse converter: 1 petabyte equals 1000000 GB.

Is this converter accurate?

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

Gigabytes to Petabytes Converter (GB to PB)

Formula

To convert gigabytes to petabytes, multiply the value by 0.000001.

PB = GB × 0.000001

Example calculation

Convert 10 GB to PB:

10 GB × 0.000001 = 0.00001 PB

Decimal vs binary: KB, MB and GB use powers of 1,000 (SI), while KiB, MiB and GiB use powers of 1,024. Storage makers use decimal units; many operating systems and memory sizes use binary ones, which is why a "500 GB" drive shows less space.

About the units

Gigabyte (GB): 1,000,000,000 bytes in the decimal system, used for drive capacity and data plans.
Petabyte (PB): 10^15 bytes in the decimal system, used in data centres and big data.
