How to convert gigabytes to terabytes
Apply the documented gigabytes-to-terabytes relationship below, keeping the full stored constant until the displayed result is rounded.
Gigabytes × 0.001 = Terabytes
For example, 10 GB equals 0.01 TB.
Gigabytes to Terabytes reference table
| Gigabytes | Terabytes |
|---|---|
| 1 GB | 0.001 TB |
| 5 GB | 0.005 TB |
| 10 GB | 0.01 TB |
| 25 GB | 0.025 TB |
| 50 GB | 0.05 TB |
| 100 GB | 0.1 TB |
Method and quality checks
- Calculation
- Gigabytes × 0.001 = Terabytes. The calculator keeps the stored factor through the operation and rounds only the displayed result to the selected or page-supported precision.
- Unit convention
- Decimal SI storage units are used: 1 GB equals 1,000 MB. Binary units such as GiB and MiB are separate units.
- Input validation
- Finite numeric inputs are accepted. Results outside the supported numeric range are rejected instead of being displayed as valid measurements.
- Reasonableness check
- 10 GB produces 0.01 TB. Check the direction and approximate scale before relying on a more precise displayed value.

Decimal gigabytes grouped into terabytes
Drive manufacturers and most storage plans use decimal prefixes: 1 terabyte equals exactly 1,000 gigabytes. A tebibyte is a different binary unit equal to 1,024 gibibytes.
- Preserve whether the source uses TB or TiB before comparing capacity.
- Do not confuse storage capacity in GB with transfer speed in Gb/s.
- Allow separately for formatting, redundancy, backups, and system-reserved space.
