Bandwidth Converters

Bandwidth — more precisely, data transfer rate — measures how much digital data moves through a connection per second. The practical everyday unit is the megabit per second (Mbps), used by ISPs to advertise broadband speeds. Two parallel systems exist: the decimal (SI) system uses powers of 1,000 (megabit = 1,000,000 bits), used by network equipment and ISPs; the binary (IEC) system uses powers of 1,024 (mebibit = 1,048,576 bits), used by some operating systems and engineers. A common confusion: ISPs advertise in megabits (Mbps) while download managers display in megabytes (MB/s) — dividing by 8 converts between them. A 100 Mbps connection delivers roughly 12.5 MB/s of actual file transfer speed.
