This video explains how to do parts per million problems as well as what ppm is used for. Percent by mass and volume are also covered here. Concentration solution unit conversion between microgram/cubic meter and part per million, part per million to microgram/cubic meter conversion in batch, mg/m3 ppm conversion chart Mass Accuracy and Resolution. Increased, measured mass accuracy and resolution is now a dominant tool for structural characterization in various applications beyond early drug discovery.

1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL.

This proportion can be used for both weight (mass) and volume.

In general the calculations are a lot easier than in the gas phase. 1 ppm solute = 10-6 kg solute / 1 kg solution = 1 mg solute / 1 kg solution There is a very convenient way to do this calculation in dilute solutions of water.

As an initialism ppm is (common) parts per million (10000 ppm = 1%).As an abbreviation ppmv is (sciences) parts per million by volume. The ppm measure simply says how many µg/g (weight) or molecules per million molecules (molar ratio) of NH3 there are in the mix.
