How to convert gigabytes to terabytes
1 gigabyte = 0.001 terabytes. To convert gigabytes to terabytes, divide by 1,000 (or multiply by 0.001). A gigabyte is 1,000,000,000 bytes under the SI definition (a gibibyte, GiB, is 1,073,741,824 bytes). A terabyte is 1,000 gigabytes under the SI definition (a tebibyte, TiB, is 1,024 GiB).
Worked examples
- 500 gigabytes = 0.5 TB (500 ÷ 1,000)
- 1,000 gigabytes = 1 TB (1,000 ÷ 1,000)
- 4,000 gigabytes = 4 TB (4,000 ÷ 1,000)
Where this conversion comes up
Gigabytes are used for phone storage, RAM, games and mobile data plans; terabytes for hard drives, SSDs and cloud backups. 1,000 GB make a terabyte (SI), so a 500 GB drive is 0.5 TB. Drive makers use SI, operating systems often use binary, which is why a '1 TB' disk shows as about 931 GB in Windows.
Quick estimate
Divide by 1,000 (binary: by 1,024).
Common mistakes
- Multiplying instead of dividing. A terabyte is larger than a gigabyte, so the number of terabytes must come out smaller: 500 gigabytes = 0.5 TB.
- Mixing decimal and binary units. Drive makers and this page use 1,000-based (SI) units; Windows reports 1,024-based sizes, which is why a 1 TB drive shows as 931 GB. The result box shows both.
