Gigabits (Gbit) to Terabytes (TB) Conversion
Gigabits
The gigabit (Gbit) is a unit of digital information equal to 1,000,000,000 bits (10⁹ bits). It is the standard for high-speed network connections: enterprise ethernet, home fibre broadband, and data centre interconnects are rated in gigabits per second (Gbps). One Gbps equals 125 megabytes per second (MB/s). Modern smartphones can receive 5G data at speeds approaching several Gbps under optimal conditions.
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.
