For example, if one was comparing the Eu content of two rocks or soils, one with a concentration of 2 ppm and the other at 1 ppm, these equate to 0.0002 and 0.0001 wt %, respectively.

One ppm is approximately equal to 0.0001percentage. PPM is used in the measurement of a small level of pollutants such as air, water, body fluids, etc. Use Percent to PPM conversion calculator to convert values from molecular weight percent to parts per million. PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg). ppm (or ppm m) is used to measure the concentration of a contaminant in soils and sediments.In that case 1 ppm equals 1 mg of substance per kg of solid (mg/kg).
