Tebibyte (TiB)
A tebibyte is 2⁴⁰ bytes, about 9.95 % more than a terabyte. A “2 TB” drive holds about 1.82 TiB, which Windows shows as “1.81 TB”.
Symbol: TiB
Quantity: amount of digital information
SI relation: 1 TiB = 8796093022208 bit (exact)
Derivation: 1 TiB = 2⁴⁰ bytes = 1,099,511,627,776 bytes.
Exact: yes, by definition
Typical uses
- Server and cloud storage quotas
- Large drives as reported by operating systems
