How to Convert Gigabytes to Zebibytes
To convert gigabytes (decimal/SI) to zebibytes (binary/IEC), multiply by 8.470329e-13. Decimal units use base 1,000, while binary units use base 1,024. You might also need: convert ZiB to Gigabytes.
GB is a decimal (SI) unit—what storage manufacturers advertise. 1 GB = 1,000 of the smaller unit. Check out our Gigabytes to Gb calculator.
ZiB is a binary (IEC) unit—what operating systems often display. 1 ZiB = 1,024 of the smaller unit. Use our MiB to Zebibytes converter.
1 GB = 8.470329e-13 ZiB (using SI decimal standard) — or equivalently, 1 ZiB = 1,180,591,620,717GB.
GB to ZiB Conversion Formula
// Convert GB to ZiB
ZiB = GB × 8.470329e-13
// Reverse: Convert ZiB to GB
GB = ZiB × 1,180,591,620,717

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. Learn more: Zettabytes to Gigabits conversion.
The gigabyte 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 Megabits Per Second to Terabytes Per Second.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Use our Gigabytes to Yobibytes calculator.
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 Zebibyte?
A zebibyte is 1,024 exbibytes or 2^70 bytes. Theoretical unit for measuring massive binary data volumes. Learn more: Yobibytes to Zebibytes converter.
The zebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. You might also need: Petabytes to Exabits.
Common uses: Theoretical storage calculations, future capacity projections, global binary data You might also need: Pbps → GB/s.
1 ZiB = 9 × 10²¹ bits = 1 × 10²¹ bytes.
The zebibyte can be abbreviated as ZiB; for example, 1 zebibyte can be written as 1 ZiB.

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