What Is a Petabyte (PB)? Definition and Uses
A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. Learn more: Megabits in Exbibytes.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our Pbps to KB/s.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives Related: PB to YiB converter.
1 PB = 8 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The petabyte can be abbreviated as PB; for example, 1 petabyte can be written as 1 PB.
What Is a Tebibyte (TiB)? Definition and Uses
A tebibyte is 1,024 gibibytes or 1,099,511,627,776 bytes. The actual usable capacity shown by operating systems. You might also need: Kb to TiB calculator.
The tebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Check out our convert YiB to Tb.
Common uses: OS-reported drive capacity, NAS actual storage, enterprise storage systems See also: Tbps → EB/s.
1 TiB = 9 × 10¹² bits = 1 × 10¹² bytes.
The tebibyte can be abbreviated as TiB; for example, 1 tebibyte can be written as 1 TiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting petabytes to tebibytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
