Gigabyte to Petabyte (GB to PB) Converter
1 gigabyte equals 0.000001 petabytes (PB) — multiply the number of gigabytes by 0.000001, or divide by 1,000,000, to convert. In the decimal (SI) system a petabyte is one million gigabytes, so a single GB is a tiny fraction of a PB.
The formula
To convert gigabytes to petabytes, multiply by 0.000001:
PB = GB × 0.000001
For example, 500 GB × 0.000001 = 0.0005 PB. To reverse it, multiply petabytes by 1,000,000.

Data-center and cloud planning happens at petabyte scale, but individual servers, backups and datasets are measured in gigabytes. Converting GB to PB lets teams roll thousands of drives into a single capacity figure and reason about large-scale storage budgets.
FAQ
How many gigabytes are in a petabyte?
One petabyte equals 1,000,000 gigabytes in decimal terms, so 1 GB = 0.000001 PB.
What is the formula to convert gigabytes to petabytes?
Multiply GB by 0.000001: PB = GB × 0.000001.
How do I convert petabytes back to gigabytes?
Multiply the petabyte value by 1,000,000. So 0.001 PB = 1,000 GB.
Is the conversion exact?
Yes, under the SI/decimal convention where 1 PB = 1,000,000 GB. Binary pebibytes (PiB) differ; this tool uses decimal units.
