Unit definitions
What is a petabyte?
The petabyte (decimal) is 1000⁵ bytes, or one thousand terabytes. It is used for data-centre storage, scientific datasets, and cloud infrastructure. Large tech platforms handle many petabytes of data.
What is a gigabyte?
The gigabyte (decimal) is one billion bytes (1000³) under the SI convention that drive and phone makers use. Movies, apps, and storage capacities are usually quoted in gigabytes. It is smaller than a gibibyte (1,073,741,824 bytes).
Frequently asked questions
How many gigabytes are in one petabyte?
One petabyte equals 1,000,000 gigabytes (1 PB = 1,000,000 GB).
How do I convert petabytes to gigabytes?
Multiply the value in petabytes by 1,000,000. For example, 10 PB × 1,000,000 = 10,000,000 GB.
Which is bigger — a petabyte or a gigabyte?
A petabyte is bigger: one petabyte contains 1,000,000 gigabytes.
Is this petabyte to gigabyte converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
