Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution. ... In the metric system ppm for mass can be expressed in terms of milligram versus kg where 1 mg/kg = 1 part per million. 3, record 1, English, - part%20per%20million

Partie par million (ppm). C'est un quotient sans dimension représentant un rapport de 10-6 (1 pour 1 million). Ce rapport peut s'appliquer par exemple à des masses ou à des volumes. Ainsi, quand on parle d'un contenu de 400 ppm (ou plus précisément ppmv [partie par million en volume]) de CO2 dans l'atmosphère, cela signifie qu'un litre d'air contient en moyenne 0,4 ml de dioxyde de carbone. 4, record 1, French, - partie%20par%20million

En general, la concentración de monóxido de carbono acompaña los cambios de densidad del tránsito que se suceden a lo lorgo del día. El descanso nocturno es suficiente para borrar la memoria de la contaminación registrada el día anterior.

Le terme anglais «billion» n'a pas la même signification aux États-Unis : 109 et en Europe : 1012, d'où le risque de confusion. Le ppb américain correspond à une concentration de 1 X 10-9, soit une partie par milliard dans la terminologie française. D'après la norme NF-X20-101 de l'AFNOR, l'emploi de puissances négatives de 10 suivies de l'indication de masse, volume, pression ou mole élimine toute confusion éventuelle. 1, record 2, French, - partie%20par%2010%5Bexposant%209%5D

Selon la source MOUSY (Guide pratique pour le système SI, de M. Moureau), les abréviations «p.p.M.» et «p.p.b.» sont interdites et il convient d'employer 10-9. Il faut souligner, cependant, que l'abréviation «ppb» est tout de même d'emploi très courant en français, en France et au Canada. Selon M. Claude Marchand et Mme Lise Bélair, traducteurs de la section Biologie du Bureau de la traduction à Montréal, l'expression «cinq parties par milliard» doit être abrégée de la façon suivante : 5 p.p. 109 (meilleure solution), ou 5 X 10-9, ou 5/p109, s'il faut absolument éviter l'emploi de «5 ppb». 1, record 2, French, - partie%20par%2010%5Bexposant%209%5D
