How to Convert Exabytes to Bytes
To convert exabytes to bytes, multiply by 1.000000000000e+18. This gives you the equivalent storage size in the target unit. Related: convert B to Exabytes.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. Use our Exabytes to Kb calculator.
B: A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). Use our Pib to Bytes converter.
1 EB = 1.000000000000e+18 B (using SI decimal standard) — which means there are 1.000000000000e+18bytes in every exabyte.
EB to B Conversion Formula
// Convert EB to B
B = EB × 1.000000000000e+18
// Reverse: Convert B to EB
EB = B × 1.000000e-18

What Is a Exabyte?
An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. Use our Pebibytes to Mebibytes conversion.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our convert Gibibytes Per Second to Mebibits Per Second.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation Learn more: Exabytes to Tebibytes calculator.
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 Byte?
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). Use our Pebibytes to Bytes converter.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: Mebibytes to Tebibytes.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) See also: bps → YB/s.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.

SI Decimal vs Binary: Why Two Different Standards?
When converting exabytes to bytes, 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
For accurate capacity planning, always verify whether specifications use SI decimal (base 1000) or binary (base 1024) units. The difference becomes significant at larger scales.
