This is not the case, because one byte contains eight bits, thus making a megabyte 8 times the size of a megabit so to download 1 MB in 1 second you need a connection speed of 8 Mbps. People often incorrectly assume that a speed of 1 Mbps will allow them to download 1 MB in 1 second. megabit (Mb) or megabit per second (Mbps, Mb/s), with a small or lowercase ‘b’, a data-rate unit used for download speeds advertised by ISPs and reported by on-line tools, equal to 1000 2 bits (b).

One thing that often causes confusion is the difference between: If you see a big difference between the Internet connection speed your provider promised you, the speed you measured with other tools or speed tests, and the speed that NetWorx or NetGenius show, it might mean that you are comparing bytes and bits.
