About these units
A data rate is the amount of data moved per second. Internet providers advertise speeds in bits per second, usually megabits (Mbps) or gigabits (Gbps), with decimal prefixes.
Browsers and download managers show bytes per second, often MB/s or MiB/s. Because a byte is 8 bits, a 100 Mbps connection delivers at most 12.5 MB/s, before protocol overhead, which usually takes a few per cent more.

Questions people ask
How many MB/s is 100 Mbps?
12.5 MB/s: divide megabits per second by 8. Real downloads are a little slower because of network overhead.
What is the difference between Mbps and MB/s?
Mbps counts megabits per second, MB/s megabytes per second. One MB/s equals 8 Mbps.
Is 1 Gbps the same as 1000 Mbps?
Yes. Network speeds always use decimal prefixes, so 1 Gbps is exactly 1000 Mbps.
