A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs.
View the terabyte data unit pageHow to Convert Gibibytes to Terabytes
To convert gibibytes (binary/IEC) to terabytes (decimal/SI), multiply by 0.001073741824. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
GiB is a binary (IEC) unit where 1 GiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations.
TB is a decimal (SI) unit where 1 TB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Related: Gibibytes to Zettabytes.
1 GiB = 0.001073741824 TB (using SI decimal standard) — or equivalently, 1 TB = 931.3225746155GiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting gibibytes to terabytes, 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 above the converter.
FAQs: Gibibyte to Terabyte Conversion
How many terabytes are in 1 gibibyte?
1 Gibibyte (GiB) equals 0.001073741824 Terabytes using the SI decimal standard.
How do I convert gibibytes to terabytes?
Multiply the gibibyte value by 0.001073741824 to get terabytes. For example, 10 GiB = 0.01073741824 TB.
Is a gibibyte bigger than a terabyte?
No. 1 GiB = 0.001073741824 TB, so the terabyte is larger — 1 TB = 931.3225746155 GiB.
What is Gibibyte (GiB) commonly used for?
