How to Convert Gigabits to Gibibytes
To convert gigabits to gibibytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity. See also: GiB to Gb calculator.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications. Try the Gb to ZiB converter.
GiB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: Mb to GiB.
1 Gb = 0.116415321827 GiB (using SI decimal standard) — or equivalently, 1 GiB = 8.589934592Gb.
Gb to GiB Conversion Formula
// Convert Gb to GiB
GiB = Gb × 0.116415321827
// Reverse: Convert GiB to Gb
Gb = GiB × 8.589934592

What Is a Gigabit?
A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. Check out our Zettabits in Exabytes.
The gigabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: converting Zebibytes Per Second to Yobibits Per Second.
Common uses: Fiber internet speeds, enterprise networking, 10GbE connections You might also need: Gb to TB conversion rate.
1 Gb = 1 × 10⁹ bits = 125 × 10⁶ bytes.
The gigabit can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.
What Is a Gibibyte?
A gibibyte is 1,024 mebibytes or 1,073,741,824 bytes. This is what operating systems actually display for storage. See also: calculate GB to GiB.
The gibibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Try the how many Gibibits in a Eib.
Common uses: Windows/macOS file sizes, SSD actual capacity, RAM modules Related: how many MB/s in Kilobits Per Second.
1 GiB = 9 × 10⁹ bits = 1 × 10⁹ bytes.
The gibibyte can be abbreviated as GiB; for example, 1 gibibyte can be written as 1 GiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting gigabits to gibibytes, 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.
