മെഗ- എന്നത്, അളവുസമ്പ്രദായത്തിലെ ഏകകപൂർവ്വപ്രത്യയം ആകുന്നു. ഇത് 106 അല്ലെങ്കിൽ 1000000 ആകുന്നു. 1960ൽ ആണിത് അന്താരാഷ്ട്ര ഏകക സമ്പ്രദായത്തിൽ ഉപയോഗിക്കാൻ തുടങ്ങിയത്. മെഗ ഗ്രീക്ക് വാക്കായ μέγας megas, ൽ നിന്നും വന്നതാണ് ഇതിന്റെ അർഥം, മഹത്തരം "great" എന്നാണ്.

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 1000 000 m by 1000 000 m or 1012 m2 , and not 1000 000 square metres (106 m2 ).
1 Mm3 means one cubic megametre or the size of a cube of 1000 000 m by 1000 000 m by 1000 000 m or 1018 m3 , and not 1000 000 cubic metres (106 m3 )
In computing , mega may sometimes denote 1,048,576 (220 ) of information units (example: a megabyte , a megaword), but denotes 1000 000 (106 ) units of other quantities, for example, transfer rates: 1megabit/s = 1000 000 bit/s . The prefix mebi has been suggested as a prefix for 220 to avoid ambiguity.

↑ The metric system was introduced in 1795 with several metric prefixes , of which, however, only six were adopted as SI prefixes by the 11th CGPM conference in 1960, whereas myria (ma, 104 ) and myrio (mo, 10-4 ) as well as double and demi were not adopted. In 1873, micro and mega were recommended by the British Association for the Advancement of Science . The other dates relate to recognition by a resolution of the CGPM.
