What unit is ppm?
parts per million
This is an abbreviation for “parts per million” and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing.
How many cubic feet are in a ppm?

How do you calculate CFM from LB to air?
CFM = (2.0 x 7200 x 90 x 2.22) / 5660 = 508.32 or 35.6lb/min. To convert this value to lb/min take CFM and divide by 14.27.
How to convert pounds per hour to ppm?
The molar mass of CO is 28, but you are working in pounds not grams, so I’ll use pound-moles. Divide the number of pounds of CO per hour by 28 to get pound-moles per hour. Now divide by the number of pound moles per hour of air you are mixing it in (or whatever you are mixing it with) and multiuply by 1 million to get ppm.
Which is bigger 1 pound per cubic foot or 1 ppm?
Always check the results; rounding errors may occur. In relation to the base unit of [density] => (kilograms per cubic meter), 1 Parts Per Million (ppm) is equal to 0.001 kilograms-per-cubic-meter, while 1 Pounds Per Cubic Foot (lb/ft3) = 16.01846337 kilograms-per-cubic-meter.
How is one part per million ( ppm ) expressed?
Another way of expressing this value is ppmv. [1] One part per million (by volume) is equal to a volume of a given gas mixed in a million volumes of air: A micro liter volume of gas in one liter of air would therefore be equal to 1 ppm:
