betyder att måttet är volymsbaserat. Vanligen avser man volymsppm även när man skriver ppm, men se upp ifall man avser viktsppm. 1 ppm = 1 ml/ 1 m3 ppm är oberoende av temperaturen, dvs det finns fortfarande x ml/m3 oberoende av tryck och temperatur. Omvandling från ppm till mg/m3

1 g O3 / m3 = 467 PPM O3 1 PPM O3 = 2.14 mg O3/m3 100 pphm (parts per hundred million) = 1 ppm (parts per million) Ozone Concentration in Air by Weight: ppm (parts per million) This unit that expresses concentration in parts per million is measured as the volume (denoted in litres [L]) of a substance found in 1L of a medium such as air. mg/m 3 (milligram per cubic metre) ppm: parts per million. Concentration by volume of one part of gas per million parts of air. This definition is only valid for gases. For liquids or solids this calculator cannot be used.
Parts per million, lyhenne ppm, on prosentin ja promillen kaltainen suhteellinen suhdeyksikkö, joka ilmaisee, kuinka monta miljoonasosaa jokin on jostakin. 1 000 ppm = 1 ‰ 10 000 ppm = 1 %. Ympäristömyrkkyjen ohjearvot, kuten suurin sallittu pitoisuus maaperässä, hengitysilmassa, juomavedessä tai ravinnossa, ilmoitetaan usein ppm:inä.
The conversion factor depends on the temperature at which you want the conversion (usually 25 degrees Centigrade in the US), as well as the ambient pressure. times in ppb or ppm. ppb (v) is parts per billion by volume (i.e., volume of gaseous pollutant per 109 volumes of ambient air).
detektionsgräns var 0,5 ppm, eller 0,7 mg/m3, och lukttröskeln hos människa är lägre (se ovan) (Sällsten, G. -13). Utredningen kunde alltså inte
1 ppm = 1 g/m3. 1 x 1 g/m3 = 1 Grams Per Cubic Meter. Always check the results; rounding errors may occur. Definition: Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ molecular weight For example: 50 mg/m 3 of NH 3 (17.03 g/mol) 24.45 x 100 ppm / 17.03 = 71.785ppm In relation to the base unit of [density] => (kilograms per cubic meter), 1 Grams Per Cubic Meter (g/m3) is equal to 0.001 kilograms-per-cubic-meter, while 1 Parts Per Million (ppm) = 0.001 kilograms-per-cubic-meter. 1 Grams Per Cubic Meter. So each ppm of methane will contribute about 16 / 1,000,000 g to each 22.4L of the gas mixture. Or (adjusting for the volume conversion to cubic metres which contain 1,000 L) 44.7 * 16 /1,000,000 g/cubic metre.
