Megabits (Mbit) to Bytes (B) 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.
Bytes
The byte is a unit of digital information equal to exactly 8 bits, capable of representing 256 distinct values (2⁸). The 8-bit grouping became standard in the 1960s because it was sufficient to encode the 128-character ASCII set with one bit to spare for error detection. The byte is the standard unit for measuring file sizes, memory capacity, and storage media. In networking, data transfer rates are expressed in bits per second — divide by 8 to convert to bytes per second.
