1% = 10000ppm. So. x (ppm) = 10000 ⋅ x (%) Example: find how many ppm are in 1.7%. x (ppm) = 10000 ⋅ 1.7% = 17000ppm. Percent to ppm … The unit of ppm and % is related to grams per liter for dilute solutions with a density of water (1 g/mL). Related concentration units are parts per thousand (ppth) Ratio of mass of solute to total mass of sample times 1,000., parts per million (ppm) Ratio of mass of solute to total mass of sample times 1,000,000., and parts per billion (ppb) Ratio of mass of solute to … Parts Per Million (ppm) Concentration Calculations.

ppm (or ppm V) is often used to describe concentrations of contaminants in air (as a volume fraction). In this case the conversion of ppm to mg/m 3 depends on the molecular weight of the contaminant. For example, 1 ppm chlorine represents one part of chlorine in one million parts of air by weight, which is 1.45 mg/m 3.
