How to Convert Bytes to Exabytes
To convert bytes to exabytes, divide by 1.000000000000e+18. This gives you the equivalent storage size in the target unit. Try the EB to B.
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 Bytes in Terabits.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. You might also need: converting Gibibits to Exabytes.
1 B = 1.000000e-18 EB (using SI decimal standard) — or equivalently, 1 EB = 1.000000000000e+18B.
B to EB Conversion Formula
// Convert B to EB
EB = B × 1.000000e-18
// Reverse: Convert EB to B
B = EB × 1.000000000000e+18
B to EB Conversion Examples
100 B = 1.000000e-16 EB
256 B = 2.560000e-16 EB
500 B = 5.000000e-16 EB
1,000 B = 1.000000e-15 EB
2,048 B = 2.048000e-15 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). Check out our GiB to PB conversion rate.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our calculate Pbps to EB/s.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) You might also need: how many Yottabytes in a B.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.
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: how many EB in Kibibytes.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: Nibbles to Yib.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation Check out our convert GiB/s to Tebibits Per Second.
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.

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