Dans l'expression «partie par 10 à la puissance 6 en volume» le mot «partie» ne fait que prendre la place du chiffre exprimant le nombre de particules en cause. Ainsi, on écrira «neuf parties par million en volume» comme suit : 9 p.p. 106, ou 9 X 10-6, ou encore 9 p/106. 1, record 1, French, - partie%20par%2010%5Bexposant%206%5D%20en%20volume

La abreviatura ppm es ambigua, ya que algunas veces se utiliza para abreviar "parte por millar" (10-3) y otras para abreviar "parte por millón" (10-6). Por esta razón es más conveniente utilizar la forma completa "parte por millón en volumen" o "parte por 106. 2, record 1, Spanish, - parte%20por%20mill%C3%B3n%20en%20volumen
