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 Volymen av 1 mol ideal gas vid 1 atm och 0 grader C är 22.414 dm3.Vi har använt 22,4 l/mol vid beräkning av nedanstående konverteringsfaktorer. Även om CO, NO osv inte är ideala gaser

Convert ppm to percent. 1% = 1/100 1ppm = 1/1000000 So 1ppm = 0.0001% So to convert from ppm to percent, divide the ppm by 10000: x(%) = x(ppm) / 10000 PPM to Microgram Per Gram Converter. Parts per million is something out of million. A unit to measure mass which is one million gram is called as microgram.

1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example: find how many percent are in 300ppm.

Momentary readouts showed high concentrations of CO, from 167 to 790 ppm ( 203–974 mg/m3), while Smoluchowskiego 11, PL–60-179 Poznan (Poland).

If a soap bubble flowmeter (~1 L/min) is used for standard preparation, a mixture containing 100 ppm CO is convenient.

Carbon monoxide (CO) is one of the most common and widely distributed air average carbon monoxide concentration by up to 23–46 mg/m3 (20–40 ppm) (1). (1991). 11. FLACHSBART, P.G. Long-term trends in United States highway 

• When the furnace was fired at 100,000 Btu/hr and 112,000 Btu/hr, the average steady-state CO concentrations in the chamber were relatively low (≤ 6 ppm) for all test conditions (blocked, disconnected vent pipe, continuous or cycled operation). • During blocked vent tests: minutes when the CO concentration was < 25 ppm and was 1 sec when the CO concentration was 75-100 ppm. The response of this sensor and that of the CO analyzer to cycling CO concentration between 50-150 ppm is shown in Figure 3. It is seen that the performance of this sensor is comparable to the response of the CO analyzer under these test conditions. Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc..

mg/m 3 (milligram per cubic metre) of CO in the chamber was negligible (≤2 ppm). • When the furnace was fired at 100,000 Btu/hr and 112,000 Btu/hr, the average steady-state CO concentrations in the chamber were relatively low (≤ 6 ppm) for all test conditions (blocked, disconnected vent pipe, continuous or cycled operation). • During blocked vent tests: Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc.
