A millillion (alternately millinillion[1][2][3][4][5], milliatillion or milletillion[6]) is equal to 103,003 in the short scale, or 106,000 in the long scale (this number is also called Platillion).[7] It is made by combining "mille" (1,000) with the standard -illion suffix, which is itself derived from "mille".
