    About terabytes and gigabytes

    Terabytes (TB). A terabyte (TB) is 1,000 gigabytes or 10^12 bytes (decimal). Hard drives and SSDs are sold in decimal terabytes.

    Gigabytes (GB). A gigabyte (GB) is 1,000,000,000 bytes (decimal). Windows reports sizes in binary gibibytes (GiB, 1,073,741,824 bytes) but labels them GB.

    Frequently asked questions

    How many gigabytes are in a terabyte?

    One terabyte equals 1,000 gigabytes.

    How do you convert terabytes to gigabytes?

    Multiply the number of terabytes by 1000. For example, 2 TB × 1000 = 2,000 GB.

    What is 8 terabytes in gigabytes?

    8 TB is 8,000 GB.

    How much is 12 terabytes in gigabytes?

    12 terabytes equals 12,000 gigabytes.

    How do I convert gigabytes back to terabytes?

    Divide by 1000, or press the ⇄ swap button above. For example, 8,000 GB ÷ 1000 = 8 TB.

    Why does my computer show a smaller size?

    Storage makers use decimal units (1 GB = 1,000,000,000 bytes) but Windows uses binary units (1 GiB = 1,073,741,824 bytes) while still writing GB. So a 1 TB drive shows as about 931 GB.
