Petabits (Pbit) to Terabytes (TB) Conversion
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.
Terabytes
The terabyte (TB) is a unit of digital information equal to 1,000,000,000,000 bytes (10¹² bytes) in SI decimal, or 1,099,511,627,776 bytes in binary convention. Consumer hard drives and SSDs are now commonly sold in 1–4 TB capacities. The entire text collection of the US Library of Congress is estimated at approximately 20 TB. In data centres, individual server storage arrays routinely exceed hundreds of terabytes.
