About converting Petabytes to Gigabytes
Petabytes (PB) and Gigabytes (GB) are both units of digital storage, so converting between them is a single multiplication: multiply your Petabytes figure by 1,000,000. Ten Petabytes comes to 10,000,000 Gigabytes, and a hundred works out at 100,000,000 Gigabytes.
Rule of thumb: going from Petabytes to Gigabytes multiplies, so the figure always grows — one Petabyte is already 1,000,000 Gigabytes. If your answer came out smaller, you have the conversion the wrong way round.
What is a Petabyte?
A petabyte is a quadrillion bytes, a scale nothing a consumer owns comes close to. It belongs to data centres, archives and scientific instruments: particle physics at CERN, genome banks, and the disk arrays that streaming services and search engines run on. It is also the point at which moving data becomes a physical problem rather than a network one — the first image of a black hole was assembled from petabytes of telescope recordings that had to be flown between observatories on hard drives, because no internet connection could carry them in reasonable time.
What is a Gigabyte?
A gigabyte is a billion bytes in SI terms, and it is the unit consumers actually shop in: phone storage, mobile data allowances, game downloads. It is also where the decimal-versus-binary split gets genuinely interesting, because the answer depends on the product. Drives and data plans are sold in decimal gigabytes; memory is not, and an "8 GB" RAM module really is 8 GiB, because memory is physically addressed in powers of two and could not be built in round decimal sizes. Windows then reports both using binary units labelled "GB".
To put both in perspective: a petabyte is data-centre scale, not anything you own, while an hour of HD streaming video runs to a few gigabytes.

Frequently asked questions
How many Gigabytes are in one Petabyte?
There are 1,000,000 Gigabytes in one Petabyte.
How do I convert Petabytes to Gigabytes?
Multiply the number of Petabytes by 1,000,000. For example, 10 Petabytes = 10,000,000 Gigabytes.
What is 100 Petabytes in Gigabytes?
100 Petabytes is equal to 100,000,000 Gigabytes.
How do I convert Gigabytes to Petabytes?
Multiply the Gigabytes value by 0.000001 (or divide by 1,000,000).
Is this Petabytes to Gigabytes conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Petabyte = 1,000,000 Gigabytes is the complete value — nothing is rounded away.
