A terabit is a multiple of the unit bit for digital information or computer storage. The prefix tera (symbol T) is defined in the International System of Units (SI) as a multiplier of 10¹² (1 trillion, short scale), and therefore 1 terabit = 10¹²bits = 1 000 000 000 000 bits = 1000 gigabits.

The terabit has the unit symbol Tbit or Tb.
