Terabytes (TB) to Gibibytes (GiB) Converter
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.

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.
