Conversion formula

Forward

gigabytes = petabytes × 1,000,000

Reverse

petabytes = gigabytes × 1.0000e-6

Example: 10 PB × 1,000,000 = 10,000,000 GB.

About both units

From

Petabyte

The petabyte equals 10¹⁵ bytes. Used for datacenter storage, scientific datasets and video archives. 1 PB could hold the text of 500 billion pages.

Real-world: Netflix total catalog: many PB. CERN LHC data: 100+ PB/year. YouTube uploads: EB scale now.

Gigabyte

The gigabyte equals 1,000,000,000 bytes (SI) or 1,073,741,824 bytes (binary, GiB). Standard unit for USB drives, SSDs, mobile-data allowances and RAM. A 64 GB phone holds about 15,000 photos.

Real-world: Smartphone: 64 GB / 128 GB / 256 GB typical. PC RAM: 16 GB / 32 GB common. UHD movie: 20–50 GB.

Tips & common mistakes

Quick tips

1 PB = 1000 TB = 10¹⁵ B.
PiB uses binary multiples — rare in everyday context.
Scale beyond PB: EB (exabyte, 10¹⁸) and ZB (zettabyte, 10²¹).

Avoid these

Using PB when TB suffices — everyday use rarely needs PB.
Mixing PB and PiB — 12.6% difference.
Ignoring tape vs spinning-disk storage economics at PB scale.

Frequently asked questions

How many gigabytes in a petabyte?

One petabyte equals 1,000,000 gigabytes.

How do I convert petabytes to gigabytes?

Multiply the petabyte value by 1,000,000 to get the equivalent in gigabytes.

What is 100 petabytes in gigabytes?
