Long scale

Long scale is the name given since at least the 1970s to the original form of -illion nomenclature first devised by Nicolas Chuquet in the 15th century,in which successive -illion names are based on powers of a million.It has become rare in the English language (the British government officially adopted Short scale in the 1970s and short scale had long been ubiquitous in American use) but is still used in some other languages in Europe and elsewhere.In France,usage shifted from long to short and then back to long.

As extended by Jacques Pelletier,the intervening powers of a thousand end in "illiard" (109 is a milliard,1015 a billiard).

The 19th century work of William Henkle was by design applicable to long or short scale (his culminating milli-millillion is 1,000,0001,000,000,the same as an Epstein system (but not Bowers) megillion).

The Epstein system leverages long scale and SI prefixes to great heights,e.g. a quettillio-illio'quettillio-illion is 1,000,000 raised to a stack of 1,000,0001,000,000 10 30 exponents that are each 1,000,00010 30.
