Convert Terabytes to Gigabytes

The TB-to-GB conversion appears often when working with digital storage data across different unit systems. Digital storage conversions help when comparing file sizes, device capacities, and download speeds — note that these use binary (1024-based) multiples.

To convert, multiply the terabytes value by 1024. Written as an equation: GB = TB × 1024.

One terabytes equals approximately 1024 GB. This means you can multiply any TB value by 1024 to get the equivalent in GB.

Worked example: 5 TB = 5120 GB. Enter your own value in the converter above for instant results.

Common mistake: Marketing often uses decimal gigabytes (1 GB = 1,000 MB) while operating systems use binary gibibytes (1 GiB = 1,024 MiB) — check which standard applies.
