    Hi!

    It's been a bit since I've posted anything quite as substantial, so here we go!

    I was brought up with what we were led to believe was the "British/French" system of numbers, known as "long scale", which many countries still use, as opposed to the "American/German" version, which apparently Britain now uses, also known as "short scale".

    The difference? The powers of ten:

    10^n 1000^n Short scale Million^n Long scale, -ard Long scale, thousand
    3 1 Thousand 0.5 Thousand Thousand
    6 2 Million 1 Million Million
    9 3 Billion 1.5 Milliard Thousand million
    12 4 Trillion 2 Billion Billion
    15 5 Quadrillion 2.5 Billiard Thousand billion
    18 6 Quintillion 3 Trillion Trillion
    21 7 Sextillion 3.5 Trilliard Thousand trillion
    24 8 Septillion 4 Quadrillion Quadrillion
    27 9 Octillion 4.5 Quadrilliard Thousand quadrillion
    30 10 Nonillion 5 Quintillion Quintillion
    33 11 Decillion 5.5 Quintilliard Thousand quintillion
    36 12 Undecillion 6 Sextillion Sextillion
    39 13 Dodecillion 6.5 Sextilliard Thousand sextillion
    42 14 Tredecillion 7 Septillion Septillion
    45 15 Quattuordecillion 7.5 Septilliard Thousand septillion
    48 16 Quindecillion 8 Octillion Octillion
    51 17 Sexdecillion 8.5 Octilliard Thousand octillion
    54 18 Septendecillion 9 Nonillion Nonillion
    57 19 Octodecillion 9.5 Nonilliard Thousand nonillion
    60 20 Novemdecillion 10 Decillion Decillion

    ...etc.

    The details of this table is probably my best backup as to why I prefer long scale to short scale.

    As you can see, the long scale directly comes from the Latin of the power of a million, but short scale comes from what seems to be a hack: "a thousand times the power of a thousand"? "One less than the power of a thousand"?

    If you're intent on using a thousands-based system, I have suggested a "power of a thousand" name below,with the added benefit that it divides directly into the long scale without having to add such a "hack factor"!

    10^n 1000^n Silly name
    3 1 Thousand
    6 2 Bisand
    9 3 Trisand
    12 4 Quadsand
    15 5 Quintsand
    18 6 Sexsand
    21 7 Septsand
    24 8 Octsand
    27 9 Nonsand
    30 10 Decsand
    33 11 Undecsand
    36 12 Dodecsand
    39 13 Tredecsand
    42 14 Quattuordecsand
    45 15 Quindecsand
    48 16 Sexdecsand
    51 17 Sepdecsand
    54 18 Octdecsand
    57 19 Nondecsand
    60 20 Viginsand

    This is obviously very tongue-in-cheek, but it's one of the times that a common usage of numbers (which I like very much) has disappointed me.

    Till next time.
