Formula

gigabytes = petabytes × 1048576

Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.

About Petabytes and Gigabytes

Petabytes (PB): About one quadrillion bytes; large-scale enterprise and cloud storage. Common uses: Cloud storage at scale (data centers), large research datasets (CERN, genomics), and major media archives.

Gigabytes (GB): About one billion bytes; the dominant unit for consumer storage capacity. Common uses: RAM capacity, smartphone and SSD storage sizes, monthly cellular data plans, and movie file sizes.

How the conversion works

Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.

The exact relationship is gigabytes = petabytes × 1048576, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.

When this conversion matters

Converting between petabytes and gigabytes comes up wherever digital storage measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
