Gigabytes to Tebibytes (GB to TiB)
1 gigabyte equals 0.0009094947018 tebibytes (rounded).
How to convert gigabytes to tebibytes
To convert gigabytes to tebibytes, multiply the number of gigabytes by 0.0009094947018. The factor is rounded to 10 significant digits. To go the other way, multiply tebibytes by 1,099.511628 (rounded).
tebibytes = gigabytes × 0.0009094947018
Example: 10 gigabytes = 0.009094947018 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
Gigabyte (GB)
1,000,000,000 bytes (decimal). Storage manufacturers and phone makers use this definition.
The gigabyte is where the decimal-versus-binary dispute turned into lawsuits. Drive makers advertise capacity in decimal units, so a 500 GB drive holds 500 billion bytes, but Windows reports sizes in binary units and shows about 465.7 of what it labels GB for the same drive. Early challenges against Western Digital and Seagate were settled, with Western Digital adding disclaimers that usable capacity may differ from the advertised figure.
A 2019 lawsuit was decided in the manufacturers' favor, with the court relying on the decimal definition. For scale, one gigabyte holds roughly an hour of standard-definition video at 2.2 Mbit/s. A single-layer DVD+R holds about 4.7 GB and a single-layer Blu-ray about 25 GB. RAM is still often sized in binary gigabytes, which the IEC would call gibibytes.
1 gigabyte = 1,000,000,000 bytes (exactly).

Tebibyte (TiB)
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).
