How to Convert Terabytes to Gibibytes
To convert terabytes (decimal/SI) to gibibytes (binary/IEC), multiply by 931.3225746155. Decimal units use base 1,000, while binary units use base 1,024. Try the how many Terabytes in a GiB.
TB is a decimal (SI) unit—what storage manufacturers advertise. 1 TB = 1,000 of the smaller unit. Use our how many Kib in Terabytes.
GiB is a binary (IEC) unit—what operating systems often display. 1 GiB = 1,024 of the smaller unit. See also: Tebibytes to GiB.
1 TB = 931.3225746155 GiB (using SI decimal standard) — which means there are 931.3225746155gibibytes in every terabyte.
TB to GiB Conversion Formula
// Convert TB to GiB
GiB = TB × 931.3225746155
// Reverse: Convert GiB to TB
TB = GiB × 0.001073741824

What Is a Terabyte?
A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Learn more: convert Pb to Nibbles.
The terabyte 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 Gibibits Per Second to bps calculator.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups Learn more: TB to Kilobytes converter.
1 TB = 8 × 10¹² bits = 1 × 10¹² bytes.
The terabyte can be abbreviated as TB; for example, 1 terabyte can be written as 1 TB.
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. Use our Megabytes to Gibibytes conversion.
The gibibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Learn more: convert Zebibits to Petabits.
Common uses: Windows/macOS file sizes, SSD actual capacity, RAM modules Check out our Tebibits Per Second to Petabits Per Second calculator.
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 terabytes 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 |
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.
