Gigabytes (GB) to Petabits (Pbit) Conversion
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.
Petabits
The petabit (Pbit) is a unit of digital information equal to 10¹⁵ bits. It is used to describe the aggregate capacity of large networks and data centre interconnects. Global internet traffic was estimated at several hundred exabits per month in 2022 — where one exabit equals 1,000 petabits. National telecommunications backbone networks and the largest internet exchange points are measured in petabits per second of total switching capacity.
