How to Convert Exabytes to Petabytes
To convert exabytes to petabytes, multiply by 1,000 (using SI decimal). Both units measure storage capacity—the difference is scale. See also: Petabytes to Exabytes converter.
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 Yottabits calculator.
PB: A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. Learn more: convert Pebibytes to Petabytes.
1 EB = 1,000 PB (using SI decimal standard) — which means there are 1,000petabytes in every exabyte.
EB to PB Conversion Formula
// Convert EB to PB
PB = EB × 1,000
// Reverse: Convert PB to EB
EB = PB × 0.001
EB to PB Conversion Examples
100 EB = 100,000 PB
256 EB = 256,000 PB
500 EB = 500,000 PB
1,000 EB = 1,000,000 PB
2,048 EB = 2,048,000 PB
Binary Standard (Base 1024)
Using binary calculation: 1 EB = 1,024 PB
100 EB = 102,400 PB
1,000 EB = 1,024,000 PB
1,024 EB = 1,048,576 PB
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 Yottabytes to Petabits 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. Learn more: MiB/s to Kibibits Per Second converter.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation Try the Exabytes to Mb 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 Petabyte?
A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. See also: convert Mb to Petabytes.
The petabyte 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 Kilobytes to Pb.

| 5 EB | 5,000 PB | 5,120 PB |
| 10 EB | 10,000 PB | 10,240 PB |
| 25 EB | 25,000 PB | 25,600 PB |
| 50 EB | 50,000 PB | 51,200 PB |
| 100 EB | 100,000 PB | 102,400 PB |
| 128 EB | 128,000 PB | 131,072 PB |
| 250 EB | 250,000 PB | 256,000 PB |

SI Decimal vs Binary: Why Two Different Standards?
When converting exabytes to petabytes, 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
Manufacturers label drives using SI decimal (base 1000). Windows divides by 1024 instead—that's why a "1 TB" drive shows as 931 GB. Same bytes, different math.
