How to Convert Exabytes to Gigabytes
To convert exabytes to gigabytes, multiply by 1,000,000,000 (using SI decimal). Both units measure storage capacity—the difference is scale. Related: GB → EB.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. Check out our Exabytes to Bits.
GB: A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. Learn more: Terabytes to Gigabytes converter.
1 EB = 1,000,000,000 GB (using SI decimal standard) — which means there are 1,000,000,000gigabytes in every exabyte.
EB to GB Conversion Formula
// Convert EB to GB
GB = EB × 1,000,000,000
// Reverse: Convert GB to EB
EB = GB × 0.000000001
EB to GB Conversion Examples
100 EB = 100,000,000,000 GB
256 EB = 256,000,000,000 GB
500 EB = 500,000,000,000 GB
1,000 EB = 1,000,000,000,000 GB
2,048 EB = 2,048,000,000,000 GB
Binary Standard (Base 1024)
Using binary calculation: 1 EB = 1,073,741,824 GB
100 EB = 107,374,182,400 GB
1,000 EB = 1,073,741,824,000 GB
1,024 EB = 1,099,511,627,776 GB
What Is a Exabyte?
An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. You might also need: Bits to Zettabytes calculator.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: convert Zebibytes Per Second to Exbibits Per Second.

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