Gigabits to Tebibytes (Gb to TiB)

1 gigabit equals 0.0001136868377 tebibytes (rounded).

How to convert gigabits to tebibytes

To convert gigabits to tebibytes, multiply the number of gigabits by 0.0001136868377. The factor is rounded to 10 significant digits. To go the other way, multiply tebibytes by 8,796.093022 (rounded).

tebibytes = gigabits × 0.0001136868377

Example: 10 gigabits = 0.001136868377 tebibytes.

Decimal prefixes (kB, MB, GB) are powers of 1,000; binary prefixes (KiB, MiB, GiB) are powers of 1,024. Storage makers use decimal; Windows reports binary but labels it GB.

About these units

Gigabit (Gb)

ComputingCurrent unit

1,000,000,000 bits (125 MB).

Gigabit is one billion bits, or 125 million bytes. In the IEC notation it is written Gbit, while IEEE 1541-2002 recommends Gb, which may be confused with GB for gigabyte. The binary counterpart, the gibibit, is 2 to the thirtieth bits. Network links and fiber are usually rated in gigabits per second, because data transfer rates are measured in decimal SI multiples.

Memory is where gigabits and binary habits collide. Chip capacity is often given in binary multiples using the ambiguous G prefix rather than the IEC Gi, so a DRAM chip advertised as 1 GB has 2 to the thirtieth bytes. The Wikipedia article on the bit says this was still causing difficulty for software designers as of 2022. When you see a gigabit rate, divide by eight for gigabytes per second.

1 gigabit = 125,000,000 bytes (exactly).

Tebibyte (TiB)

ComputingCurrent unit

Exactly 2⁴⁰ bytes, about 9.9% larger than a terabyte.

At tera scale the two systems drift furthest apart among the common units. The tebibyte equals 2 to the fortieth bytes, or 1,099,511,627,776 bytes, and the IEC created the bi prefixes in 1998 to separate powers of 1,024 from SI powers of 1,000. A power-of-10 terabyte is about 9 percent smaller than a tebibyte, so the gap has more than tripled since the kibibyte, which is only about 2.4 percent larger than a kilobyte.

Practical consequences are visible on any new drive. A 1 TB drive may be reported as about 931 GB by an operating system that counts in binary but labels it GB. Some systems use TB for 1,024 to the fourth bytes, but the JEDEC standard does not mention TB or larger units. The unit is defined in IEC 80000-13, and its TiB symbol is rarely used outside tools such as KDE and Qt-based applications.

1 tebibyte = 1,099,511,627,776 bytes (exactly).
