GB to TB Conversion Formula
Here's the exact GB to TB formula in copy-paste-ready form — multiply by 0.001 to go from gigabytes to terabytes, or by 1,000 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert GB to TB
TB = GB × 0.001
// Reverse: Convert TB to GB
GB = TB × 1,000
Gigabyte to Terabyte Conversion Examples
100 GB = 0.1 TB
256 GB = 0.256 TB
500 GB = 0.5 TB
1,000 GB = 1 TB
2,048 GB = 2.048 TB
Binary Standard (Base 1024)
Using binary calculation: 1 GB = 0.0009765625 TB
100 GB = 0.09765625 TB
1,000 GB = 0.9765625 TB
1,024 GB = 1 TB

SI Decimal vs Binary: Why Two Different Standards?
When converting gigabytes 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.
Want to skip the ambiguity entirely? Gibibyte (GiB) and Tebibyte (TiB) are the IEC binary-only siblings of gigabyte and terabyte — always base 1,024, no dual-standard guessing. See the GiB to TiB converter.
FAQs: Gigabyte to Terabyte Conversion
How many terabytes are in 1 gigabyte?
1 Gigabyte (GB) equals 0.001 Terabytes using the SI decimal standard, or 0.0009765625 TB using the binary (IEC) standard.
How do I convert gigabytes to terabytes?
Multiply the gigabyte value by 0.001 to get terabytes. For example, 10 GB = 0.01 TB.
Is a gigabyte bigger than a terabyte?
No. 1 GB = 0.001 TB, so the terabyte is larger — 1 TB = 1,000 GB.
What is Gigabyte (GB) commonly used for?
Movies, video games, smartphone storage, USB drives, cloud storage plans.
