Mega - Definition and Overview

Mega (symbol M) is a SI prefix in the SI system of units denoting a factor of 106, i.e. one million; 1 000 000.

Confirmed in 1960, it comes from the Greek μέγας, meaning great.

For example, 1 MW (megawatt) = 1 000 000 watts = 1 000 kilowatts.

Computing

In computing, mega can sometimes denote 1,048,576 (220) of information units (example: a megabyte, a megaword), but can denote 1 000 000 (106) of other quantities, for example, transfer rates: 1 megabit/s = 1 000 000 bit/s.

The prefix mebi has been suggested as an alternative for 220 to avoid ambiguity, but is yet to be widely used.
