What Is a Exabyte?
An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. See also: Zettabytes to Pib.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: how many EB/s in Zettabits Per Second.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation Related: how many Gibibits in a EB.
1 EB = 8 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exabyte can be abbreviated as EB; for example, 1 exabyte can be written as 1 EB.
What Is a Exbibyte?
An exbibyte is 1,024 pebibytes or 2^60 bytes. Used for hyperscale storage in binary measurements. Try the calculate Mib to EiB.
The exbibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Try the b to TiB conversion rate.
Common uses: Hyperscale data centers, global storage statistics in binary, cloud provider capacity Learn more: converting Mebibytes Per Second to Kibibits Per Second.
1 EiB = 9 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exbibyte can be abbreviated as EiB; for example, 1 exbibyte can be written as 1 EiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting exabytes to exbibytes, 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.
