The gigabyte
The gigabyte (GB) equals 1,000,000,000 bytes. The difference between GB (decimal) and GiB (binary, 1,073,741,824 B) is the reason a '1 TB' drive shows as ~931 GB in Windows.
12 Gigabytes to Terabytes
12 GB = 0.012 TB (gigabyte → terabyte)
12 GB = 0.012 TB

When to use gigabytes → terabytes
Gigabytes to terabytes divides by 1000. Cloud storage billing tiers cross this boundary constantly — many providers price the first several hundred GB one way and switch pricing structure past 1 TB, so knowing exactly when 999 GB of usage becomes 1.0 TB (and triggers a different billing bracket) is a real cost-management question, not just a unit curiosity.
Enterprise licensing agreements often price storage in bands that straddle this boundary: a contract billing a per-GB rate up to 1 TB, then a discounted rate beyond, means precisely tracking whether 950 GB of usage has crossed into the 1.0 TB bracket is a real monthly cost question for a finance team, not a rounding nicety.
