The megabit is a unit of information storage, abbreviated Mbit or sometimes Mb.
1 megabit = 106 = 1,000,000 bits which is equal to 125,000 bytes or 122 kilobytes.
The megabit is most commonly used when referring to data transfer rates in network speeds, e.g. a 100 Mbit/s Fast Ethernet connection. In this context, like elsewhere in telecommunications, it always equals 106 bits. Residential high speed internet is often measured in megabits.
A binary counterpart of megabit, useful for measuring RAM and ROM chip capacity, is mebibit.
