How to Convert Gigabytes to Exabytes
To convert gigabytes to exabytes, divide by 1,000,000,000 (using SI decimal). Both units measure storage capacity—the difference is scale. Learn more: EB → GB.
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. See also: Gigabytes to Kilobytes.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. Related: Mebibits to Exabytes converter.
1 GB = 0.000000001 EB (using SI decimal standard) — or equivalently, 1 EB = 1,000,000,000GB.
GB to EB Conversion Formula
// Convert GB to EB
EB = GB × 0.000000001
// Reverse: Convert EB to GB
GB = EB × 1,000,000,000
GB to EB Conversion Examples
100 GB = 0.0000001 EB
256 GB = 0.000000256 EB
500 GB = 0.0000005 EB
1,000 GB = 0.000001 EB
2,048 GB = 0.000002048 EB
Binary Standard (Base 1024)
Using binary calculation: 1 GB = 9.313226e-10 EB
100 GB = 0.000000093132257 EB
1,000 GB = 0.000000931322575 EB
1,024 GB = 0.000000953674316 EB
What Is a Gigabyte?
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. You might also need: Terabytes to Zebibits calculator.
The gigabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: convert Kilobits Per Second to Megabytes Per Second.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Use our Gigabytes to Pebibits conversion.
1 GB = 8 × 10⁹ bits = 1 × 10⁹ bytes.
The gigabyte can be abbreviated as GB; for example, 1 gigabyte can be written as 1 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. Try the Tib to Exabytes converter.
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 Kilobytes to Gb calculator.

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