About converting Gigabytes to Terabytes
Gigabytes (GB) and Terabytes (TB) are both units of digital storage, so converting between them is a single multiplication: multiply your Gigabytes figure by 0.001. Ten Gigabytes comes to 0.01 Terabytes, and a hundred works out at 0.1 Terabytes.
Rule of thumb: going from Gigabytes to Terabytes divides, so the figure always shrinks — it takes about 1,000 Gigabytes to make a single Terabyte. If your answer came out bigger, you have the conversion the wrong way round.
What is a Gigabyte?
A gigabyte is a billion bytes in SI terms, and it is the unit consumers actually shop in: phone storage, mobile data allowances, game downloads. It is also where the decimal-versus-binary split gets genuinely interesting, because the answer depends on the product. Drives and data plans are sold in decimal gigabytes; memory is not, and an "8 GB" RAM module really is 8 GiB, because memory is physically addressed in powers of two and could not be built in round decimal sizes. Windows then reports both using binary units labelled "GB".
What is a Terabyte?
A terabyte is a trillion bytes, and it is the unit that makes the decimal-versus-binary confusion impossible to ignore: buy a 1 TB drive, plug it into Windows, and it reports roughly 931 GB. Nothing is missing and nobody has short-changed you — the manufacturer counted in decimal terabytes, as SI defines them and as this site does, while Windows divided by 1,024 three times and still wrote "GB" on the result. The honest label for what Windows shows is 931 GiB. macOS and Linux mostly report decimal now; Windows still does not.
To put both in perspective: an hour of HD streaming video runs to a few gigabytes, while a 1 TB drive shows up as about 931 GB in Windows.
