Arsenik (As).

The part/million (ppm) to gram/liter [g/L] conversion table and conversion steps are also listed. Also, explore tools to convert part/million (ppm) or gram/liter to other concentration - solution units or learn more about concentration - solution conversions.

This unit expressed the concentration of a pollutant as the ratio of its volume if segregated pure, to the volume of the air in which it is contained. One part per million (ppm) denotes one part per 1,000,000 (10 6) parts, and a value of 10 −6. It is equivalent to about 32 seconds out of a year or 1 mm of error per km of distance traversed. One part per billion (ppb) denotes one part per 1,000,000,000 (10 9) parts, and a value of 10 −9.

It is equivalent to about 32 seconds out of a year or 1 mm of error per km of distance traversed. One part per billion (ppb) denotes one part per 1,000,000,000 (10 9) parts, and a value of 10 −9. 500 ppm motsvarar alltså 0,5 promille. Vi kan räkna på samma sätt med procent, då vi vet att en procent på grundpotensform kan skrivas som.
