Terabits (Tbit) to Gigabytes (GB) Conversion
Terabits
The terabit (Tbit) is a unit of digital information equal to 1,000,000,000,000 bits (10¹² bits). It is used to express the capacity of high-speed backbone network links and submarine cables: major undersea cables connecting continents operate at capacities measured in terabits per second (Tbps). One terabit per second equals 125 gigabytes per second — the scale of internet exchange points and national backbone infrastructure.
Gigabytes
The gigabyte (GB) is a unit of digital information equal to 1,000,000,000 bytes (10⁹ bytes) in SI decimal, or 1,073,741,824 bytes in binary convention. It is the dominant unit for consumer storage — smartphone internal storage, USB drives, and SD cards are sold in gigabytes. One hour of standard HD streaming consumes approximately 3 GB; one hour of 4K video requires 7–15 GB depending on encoding. Monthly mobile data plans are universally priced per gigabyte.
