Orders of magnitude of data

A terabit is a unit of information or computer storage, abbreviated Tbit (or Tb).

1 terabit = 10¹² bits = 1,000,000,000,000 bits (one trillion, or, using the long scale, one billion). 1 terabit is equal to 1,000 (decimal) gigabytes and a tebibit to 1024 (binary) gibibytes.

The terabit is closely related to the tebibit, which is equal to 2⁴⁰ or 1,099,511,627,776 bits. Note that the difference between a trillion bits and a tebibit is about 10%.But in normal computer parlance a terabit would really refer to a tebibit of 10⁴⁰
