Overview

About converting gigabytes to terabytes

Gigabytes to terabytes scales individual file and drive sizes up to the terabyte capacities of modern disks and cloud plans.

One terabyte is 1,024 gigabytes in the binary convention, so converting gigabytes to terabytes means dividing by 1,024. A 512 GB SSD is 0.5 TB, and 2,048 GB is exactly 2 TB.

As with smaller units, drive manufacturers usually advertise terabytes in decimal (1,000 GB), so a '1 TB' drive holds about 931 binary GB once formatted. For backups and media libraries, knowing this gap prevents the unpleasant surprise of a drive that seems smaller than promised.

Practical Tips

Binary: divide GB by 1,024. Decimal: divide by 1,000.
A '1 TB' marketed drive ≈ 931 GB as your operating system counts it.
