    For the same magnitude name (n-illion), the value is 10 3n+3 in the short scale but 10 6n in the long scale for positive integers n. [ 4 ] [ 1 ] [ 2 ] In some languages, the long scale uses additional names for the intermediate multipliers, replacing the ending -ion with -iard ; for example, the next multiplier after million is milliard (10 9 ...

  4. Order of magnitude - Wikipedia

    en.wikipedia.org/wiki/Order_of_magnitude

    However, 1 and 15 are not within an order of magnitude, since their ratio is 15/1 = 15 > 10. The reciprocal ratio, 1/15, is less than 0.1, so the same result is obtained. Differences in order of magnitude can be measured on a base-10 logarithmic scale in " decades " (i.e., factors of ten). [ 2 ]
