GB is a decimal (SI) unit—what storage manufacturers advertise. 1 GB = 1,000 of the smaller unit. You might also need: Gigabytes to Tb.
TiB is a binary (IEC) unit—what operating systems often display. 1 TiB = 1,024 of the smaller unit. Use our convert Tib to Tebibytes.
1 GB = 0.000909494702 TiB (using SI decimal standard) — or equivalently, 1 TiB = 1,099.511628GB.
GB to TiB Conversion Formula
// Convert GB to TiB
TiB = GB × 0.000909494702
// Reverse: Convert TiB to GB
GB = TiB × 1,099.511628

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. Try the Yottabits to Tb 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. See also: ZiB/s to Mebibits Per Second converter.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Try the Gigabytes to Zettabits 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 Tebibyte?
A tebibyte is 1,024 gibibytes or 1,099,511,627,776 bytes. The actual usable capacity shown by operating systems. You might also need: convert Zettabits to Tebibytes.
The tebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Use our Megabytes to Exbibits calculator.
Common uses: OS-reported drive capacity, NAS actual storage, enterprise storage systems Check out our Gibibytes Per Second to Gibibits Per Second converter.
1 TiB = 9 × 10¹² bits = 1 × 10¹² bytes.
The tebibyte can be abbreviated as TiB; for example, 1 tebibyte can be written as 1 TiB.

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