How to convert petabytes to gigabytes
To convert a measurement in petabytes to gigabytes, multiply the value by 1,000,000. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 PB to gigabytes: 5 × 1,000,000 = 5,000,000 GB.
What is a petabyte?
A petabyte is 1,000,000,000,000,000 bytes (1,000 terabytes) under the SI decimal convention. The binary equivalent is the pebibyte (PiB). The petabyte is the scale of large enterprises and cloud providers. Notable milestones include estimates that major platforms ingest multiple petabytes of new data every day.
Common uses of petabytes include: Data-center and cloud-storage capacity; Big-data analytics and data lakes; Scientific datasets (genomics, astronomy); Large-scale media streaming archives.
What is a gigabyte?
A gigabyte is 1,000,000,000 bytes (1,000 megabytes) under the SI decimal convention. The binary equivalent of 1,073,741,824 bytes is the gibibyte (GiB). The gigabyte became the standard consumer storage unit with the rise of hard drives, USB sticks, and smartphones. Drive makers market capacity in decimal gigabytes, while operating systems often report in binary gibibytes, which is why a '500 GB' drive shows as about 465 GB.
Common uses of gigabytes include: Hard drive, SSD, and USB flash storage capacity; Smartphone and tablet storage tiers; HD video and large software installs; RAM and memory-card sizing.

1 PB = 1,000,000 GB 5 PB = 5,000,000 GB 10 PB = 10,000,000 GB 50 PB = 50,000,000 GB 100 PB = 100,000,000 GB
Frequently asked questions
How many gigabytes are in one petabyte?
One petabyte (PB) equals 1,000,000 gigabytes (GB). Multiply any value in petabytes by 1,000,000 to convert to gigabytes.
How do I convert petabytes to gigabytes?
Multiply the value in petabytes by 1,000,000. For example, 5 PB × 1,000,000 = 5,000,000 GB.
How do I convert gigabytes to petabytes?
Multiply the value in gigabytes by 0.000001, or divide by 1,000,000. Use the swap button on the converter above to reverse the direction.
Is the petabyte to gigabyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for petabytes to gigabytes?
The formula is: GB = PB × 1,000,000. This comes from the definition of both units relative to the byte.
