for use in the International System of Units in 1960. Mega comes from the Greek μέγας

megas, meaning "great".

Other common examples of usage megapixel - 1 million pixels in a digital

camera one megatonne is the approximate energy released

on igniting one million tonnes of TNT. megahertz — frequency of electromagnetic

radiation for radio and television broadcasting, GSM, etc. 1 MHz = 1,000,000 Hz.

Exponentiation When units occur in exponentiation, such as

in square and cubic forms, any size prefix is considered part of the unit, and thus included

in the exponentiation. 1 Mm2 means one square megametre or the size

of a square of 1000000m by 1000000m or 1012m2, and not 1000000square metres.

1 Mm3 means one cubic megametre or the size of a cube of 1000000m by 1000000m by 1000000m

or 1018 m3, and not 1000000cubic metres Computing

In computing, mega may sometimes denote 1,048,576 of information units, but denotes 1000000

units of other quantities, for example, transfer rates: 1megabit/s = 1000000bit/s. The prefix

mebi has been suggested as a prefix for 220 to avoid ambiguity.
