A conversion of mg/kg to ppm is 1:1. To convert to parts per million, you don't need to do anything other than take the mg/kg off the end and add ppm on to the end.To explain: 1 mg = 0.001 grams. 1 kg = 1,000 grams. 0.001 / 1,000 = 1/1,000,000 = one ppm. conversion of mg/kg to ppm is 1:1. To convert to parts per million, you don't need to do anything other than take the mg/kg off the end and add ppm on to the end.
You can use both parts per million (ppm) and milligrams per kilogram (mg/kg) to describe the concentration of one compound dispersed in another. Scientists often use these units of concentration to provide information about the concentration of especially dilute solutions.or example, if your measurement value was 328 parts per million, you would write out 328. Write the units mg/kg after your numerical value. In the case of the example, you would write out 328 mg/kg. This is all that is required because parts per million on a mass per mass basis are identical to milligrams per kilogram.
