The petabit is a multiple of the unit bit for digital information or computer storage. The prefix peta (symbol P) is defined in the International System of Units (SI) as a multiplier of 1015 (1 quadrillion, short scale), and therefore 1 petabit = 1015 bits = 1 000 000 000 000 000 bits = 1000 terabits. The petabit has the unit symbol Pbit or Pb.
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.
