Mega

From Free net encyclopedia

mega- (symbol M) is an 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. The Greek μεγας (μεγας,μεγαλη,μεγα) comes in turn from the Sanskrit maha, 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.
