Megabits (Mbit) to Terabytes (TB) Conversion
Megabits
The megabit (Mbit) is a unit of digital information equal to exactly 1,000,000 bits (10⁶ bits). It is the standard unit for expressing internet connection speeds: a "100 Mbps" broadband connection transfers 100 million bits per second, equivalent to 12.5 megabytes (MB/s). This factor-of-8 difference between megabits and megabytes is a frequent source of consumer confusion when comparing marketed connection speeds against actual file download rates.
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.
