Editing Long and short scales (section)

==Definition==
In both scales, names are given to orders of magnitude at increments of 1000. Both systems use the same names for magnitudes less than 10<sup>9</sup>. Differences arise from the use of identical names for larger magnitudes. For the same magnitude name (''n''-illion), the value is 10<sup>3''n''+3</sup> in the short scale but 10<sup>6''n''</sup> in the long scale for positive integers ''n''.<ref name="pilatol1" /><ref name="Guitel1" /><ref name="Guitel2" />

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<sup>9</sup>); after a ''billion'' it is ''billiard'' (10<sup>15</sup>). Hence, a long scale ''n''-illiard equals 10<sup>6''n''+3</sup>.

The following table shows the size of first few short and long scale magnitudes. Notice how billion and trillion are in both scales but have different sizes.
