Du kan konvertera från mg /m3 till ppm genom att först beräkna molekylvikten för kemikalien. Instant free online tool for part/million (ppm) to gram/liter conversion or vice versa. 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. ((LPM x 60) x 0.001) x g/m3 = g/hr This calculation works the same regardless of feed-gas type (air or oxygen) as a mass (grams) is used in the calculation, therefore it is a direct calculation.

To convert ozone concentration in air to another unit of measure use the calculator below Comprehensive, user-friendly humidity calculator supporting all popular parameters including dew/frost-point, %rh, ppmV, moisture content and more. 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.

2008-08-10 · So how we should work to transfer ppm to mg/m3 at first let look for example when we have concentration of 35 ppm SO2. This mean that in one cubic meter we have 1 000 000 cubic centimeters. Then if we have 35 ppm this means that in one cubic meter there is 35 cubic centimeters of sulfur dioxide – 35 cm3/m3.

Simply enter a value in one of the fields, choose a preset gas type in the drop down menu, enter a pressure value and then press the calculate button. If the gas type is not listed, enter known molecular weight instead. The SI unit of volume is the cubic meter (m3). Suppose a constituent of a gaseous mixture is at a concentration of 1 ppm. If one were to separate the mixture into its components, and measure the volume of each component, there would be 1 m3of the gas of interest for every 106 m3of the mixture. 1 m3constituent/106 m3of the mixture = 1 ppm Absolute Humidity 0 kg/m3 .
