Permil


The use of permil (a.k.a. parts per thousand) is a way of expressing ratios in terms of whole numbers. Given a ratio or fraction, it is converted to a permil-age by multiplying by 1000 and appending a "mil sign" %%. For example, if an investment grows from a number P=13.00 to a number A=22.50, then A is 22.50/13.00=1.7308 times as much as P, or 1730.8%%.
