Megabits (Mbit) to Kilobytes (kB) 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.
Kilobytes
The kilobyte (kB) is a unit of digital information equal to 1,000 bytes in the SI decimal system. In the binary convention historically used by operating systems, 1,024 bytes was called a kilobyte — now formally named a kibibyte (KiB). Hard drive manufacturers use the decimal definition, while operating systems historically used binary values, making a "500 GB" drive appear as roughly 465 GB in Windows. Plain-text documents, small images, and configuration files are measured at the kilobyte scale.
