- Round to desired decimal places
About Gigabytes and Petabytes
Gigabyte (GB)
A gigabyte represents approximately 1 billion bytes of data storage. It’s commonly used to measure file sizes, RAM capacity, and storage space on personal devices.
Decimal: 1,000,000,000 bytes
Binary: 1,073,741,824 bytes
Petabyte (PB)
A petabyte equals approximately 1 quadrillion bytes. It’s used for massive data centers, enterprise storage systems, and large-scale cloud infrastructure.
Decimal: 1,000,000,000,000,000 bytes
Binary: 1,125,899,906,842,624 bytes
Decimal vs Binary Systems
There are two main systems for measuring digital storage:
- Decimal System (SI): Based on powers of 10 (1000). Used by storage manufacturers and most operating systems for marketing. 1 GB = 1,000,000,000 bytes.
- Binary System (IEC): Based on powers of 2 (1024). More accurate for computer memory and actual storage calculations. 1 GB = 1,073,741,824 bytes.
Why the difference matters: When you buy a 1 TB hard drive, it contains 1,000,000,000,000 bytes (decimal). However, your computer may show it as 931 GB because it calculates using binary (1,099,511,627,776 bytes = 1 TB binary). This is why advertised storage capacity appears smaller when formatted.

Frequently Asked Questions
How many gigabytes are in a petabyte?
In the decimal system (SI), 1 petabyte equals exactly 1,000,000 gigabytes. In the binary system (IEC), 1 petabyte equals 1,048,576 gigabytes. Most consumer applications use the decimal system.
Which system should I use for conversion?
Use the decimal system for hard drives, SSDs, and storage device capacities as manufacturers advertise using this standard. Use the binary system for RAM, processor cache, and precise computer memory calculations.
Why do hard drives show less space than advertised?
Storage manufacturers use the decimal system (1 GB = 1,000,000,000 bytes), while operating systems often calculate using the binary system (1 GB = 1,073,741,824 bytes). This creates a discrepancy where a “1 TB” drive shows as approximately 931 GB in your system.
How much is 100 GB in petabytes?
100 gigabytes equals 0.0001 petabytes in the decimal system. To convert, simply divide 100 by 1,000,000, which gives you 0.0001 PB.
What comes after petabytes?
The next unit after petabytes is exabytes (EB). 1 exabyte equals 1,000 petabytes or 1,000,000,000 gigabytes in the decimal system. Beyond that are zettabytes (ZB) and yottabytes (YB).
Can I convert GB to PB for network bandwidth?
For network speeds, you typically measure in bits (Gb, Pb) rather than bytes (GB, PB). Remember that 1 byte = 8 bits, so 1 GB = 8 Gb. Always verify whether you’re working with bits or bytes before converting.
Is 1000000 GB exactly 1 PB?
Yes, in the decimal (SI) system, 1,000,000 GB equals exactly 1 PB. However, in the binary (IEC) system, you need 1,048,576 GB to equal 1 PB. Always check which system your context requires.
How do I calculate large GB values to PB quickly?
For a quick mental calculation using the decimal system, simply move the decimal point six places to the left. For example, 5,000,000 GB becomes 5.0 PB. For more precise calculations, use the conversion formulas provided above.
