About Data Transfer Rate Conversions
Data transfer rate measures how fast data moves over a network connection. Internet providers advertise speeds in bits per second, and broadband and mobile plans are sold in megabits per second (Mbps). File managers and download bars show bytes per second (MB/s) instead. Since 1 byte is 8 bits, a 100 Mbps connection tops out around 12.5 MB/s in practice. That is why a download so often looks slower than the internet plan promises. This converter uses decimal SI prefixes (1 kbit/s = 1,000 bit/s), as internet providers and network equipment do. Storage sizes, by contrast, sometimes use binary prefixes.
Typical Connection Speeds
Providers advertise bits per second, downloads show bytes per second. Divide by 8: a 100 Mbit/s line tops out near 12.5 MB/s.

History of data rates
Data rates count bits per second, with decimal prefixes: 1 Mbit/s is 1,000,000 bits per second. A byte is 8 bits, so a 100 Mbit/s connection moves 12.5 MB each second.
- Claude Shannon showed that every communication channel has a maximum rate, in bits per second, at which it can carry information with as few errors as desired.
- Ethernet became the IEEE 802.3 standard, carrying 10 Mbit/s over thick coaxial cable.
- Ethernet reached 400 Gbit/s, forty thousand times the speed of the first standard.
