petabyte to gigabyte
Convert petabyte (PB) to gigabyte (GB). Use an editable data storage converter, conversion formula, and reference table.
1 PB = 1,000,000 GB
Conversion formula
One petabyte equals 1,000,000 gigabyte. Multiply your value in petabyte by this factor to get gigabyte. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 petabyte:5 × 1,000,000 = 5,000,000 GB

About these measurements
Data storage expresses a number of bits or bytes.
The base reference used here is the byte. One petabyte is 1e+15 base units; one gigabyte is 1,000,000,000 base units.
Important distinctions
Decimal prefixes use powers of 1,000; binary prefixes use powers of 1,024. One byte is eight bits.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert PB to GB?
Multiply the quantity in PB by 1,000,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the gigabyte to petabyte converter.
