Formula
gigabytes = terabytes × 1024
Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.
About Terabytes and Gigabytes
Terabytes (TB): About one trillion bytes; modern hard drives and SSDs reach into the terabyte range. Common uses: Hard drive capacity, server storage, backup systems, and large dataset sizes.
Gigabytes (GB): About one billion bytes; the dominant unit for consumer storage capacity. Common uses: RAM capacity, smartphone and SSD storage sizes, monthly cellular data plans, and movie file sizes.
How the conversion works
Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.
The exact relationship is gigabytes = terabytes × 1024, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between terabytes and gigabytes comes up wherever digital storage measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
