How to Convert Gigabytes to Yobibytes
To convert gigabytes (decimal/SI) to yobibytes (binary/IEC), multiply by 8.271806e-16. Decimal units use base 1,000, while binary units use base 1,024. Use our YiB to GB converter.
GB is a decimal (SI) unit—what storage manufacturers advertise. 1 GB = 1,000 of the smaller unit. Try the GB to Yb calculator.
YiB is a binary (IEC) unit—what operating systems often display. 1 YiB = 1,024 of the smaller unit. You might also need: convert Mib to YiB.
1 GB = 8.271806e-16 YiB (using SI decimal standard) — or equivalently, 1 YiB = 1.208925819615e+15GB.
GB to YiB Conversion Formula
// Convert GB to YiB
YiB = GB × 8.271806e-16
// Reverse: Convert YiB to GB
GB = YiB × 1.208925819615e+15

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. Check out our EiB → EB.
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: Petabytes Per Second to Pebibytes Per Second.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Learn more: Gigabytes to Terabytes converter.
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 Yobibyte?
A yobibyte is 1,024 zebibytes or 2^80 bytes. The largest IEC binary unit currently defined. See also: Megabytes to Yobibytes calculator.
The yobibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Use our convert Bytes to Zebibytes.
Common uses: Theoretical storage limits, far-future capacity projections, academic discussions Related: Tebibits Per Second to Zettabits Per Second conversion.
1 YiB = 10 × 10²⁴ bits = 1 × 10²⁴ bytes.
The yobibyte can be abbreviated as YiB; for example, 1 yobibyte can be written as 1 YiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting gigabytes to yobibytes, 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
The ~9.95% difference between binary and decimal units compounds at each level. A 1 TB drive shows as 931 GiB in Windows because of this standard mismatch—no space is actually lost.

When to Convert GB to YiB
Common scenario: Reconciling the difference between what drive manufacturers advertise and what your operating system displays. You might also need: GB to Exbibits converter.
Other situations include storage planning for calculating how much data fits in a given capacity, file management for understanding sizes across different scales, cost estimation for budgeting cloud storage, and backup planning for determining media requirements.
