ONLINE ETYMOLOGY DICTIONARY:

omega

c.1400, from Medieval Greek omega, from classical Greek o mega "big 'o' " (in contrast to o micron "little 'o' "); so called because the vowel was long in ancient Greek. From mega (see mega-). The final letter of the Greek alphabet, hence used figuratively for "the last, final" of anything (cf. Rev. i:8),

mega-

before vowels meg-, prefix often meaning "large, great," but in precise scientific language "one million" (megaton, megawatt, etc.), from Gk. megas "great, large, vast, big, high, tall; mighty, important" (fem. megale), from PIE *meg- "great" (cf. L. magnus, O.E. micel; see mickle). Mega began to be used alone as an adjective by 1982.
