What Is a Pebibyte?
A pebibyte is 1,024 tebibytes or 2^50 bytes. Used for large-scale enterprise storage in binary terms. See also: Eib → Pib.
The pebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. You might also need: convert Yibps to bps.
Common uses: Enterprise SAN storage, data center capacity planning, cloud infrastructure Try the PiB to Yib calculator.
1 PiB = 9 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The pebibyte can be abbreviated as PiB; for example, 1 pebibyte can be written as 1 PiB.
What Is a Gigabit?
A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. See also: b to Gb converter.
The gigabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Try the EiB to Kb.
Common uses: Fiber internet speeds, enterprise networking, 10GbE connections You might also need: Yottabytes Per Second in Zebibytes Per Second.
1 Gb = 1 × 10⁹ bits = 125 × 10⁶ bytes.
The gigabit can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.

SI Decimal vs Binary: Why Two Different Standards?
When converting pebibytes to gigabits, 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 |
Why Does My Hard Drive Show Less Space Than Advertised?
This difference in standards explains the common "missing hard drive space" confusion.
Example: A "500 GB" Hard Drive
- Contains exactly: 500,000,000,000 bytes
- macOS (SI Decimal): Displays 500 GB (divides by 1,000³)
- Windows (Binary): Displays 465 GB (divides by 1,024³)
The Verdict: Same bytes, same drive—just different math. No space is actually missing.
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.
💡 Storage Engineer Tip
The ~9.95% difference between binary and decimal units compounds at each level. A 1 TB drive shows as 931 GiB in Windows because of this standard mismatch—no space is actually lost.
