Was wird mit PPM angegeben?
Die Einheit ppm (parts per million) gibt die Anzahl der Teile pro 1 Million Teilen an. Es ist deshalb möglich, eine direkte Umrechnung in Volumen / Volumen oder Gewicht / Gewicht vorzunehmen. 1 ppm bedeutet dann z.B. 1 ml / m3 oder 1 mg / Kg. Es wird also immer in gleichen Einheiten gerechnet.

What is the difference between pPb and ppbv?
Re: What is the difference between ppb and ppbv. bbp is usually a mass ratio: 1 g of solute per 109 grams of solution. bbpv would be a volume ration: 1 mL of solute per 109 mL of solution, since the density of most substance is not one (with the exception of water ), the two ratios would not be the same.
How do you convert ppb to ppm?
How to convert ppb to ppm. ppm and ppb are defined as: 1ppm = 1/10 6 = 10 -6. 1ppb = 1/10 9 = 10 -9. So. 1ppm = 1000ppb. The number of parts-per million x ppm is equal to the number of parts-per billion x ppb divided by 1000: x ppm = x ppb / 1000.
What is the conversion factor of ppb to moles?
For example, the conversion factor between a mass fraction of 1 ppb and a mole fraction of 1 ppb is about 4.7 for the greenhouse gas CFC-11 in air. For volume fraction, the suffix „V“ or „v“ is sometimes appended to the parts-per notation (e.g., ppmV, ppbv, pptv).
What is 1 part per billion (ppb) equivalent to?
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. This is equivalent to about three seconds out of a century.
