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.
PPM-Parts Per Million: Number of grams of solute per 1 million grams of solution. ppm=[mass of solute/mass of solution]*10 to the 6th power.&. PPB-Parts Per Billion: Number of grams of solute per 1 billion grams of solution.ppb=[mass of solute/mass of solution]*10 to the 9th power. The unit is used to calculate the concentration ofâ¦. 2  How Strong Is that Solution: The Definition of PPM Chemistry often works with solutions of substances such as acid and water, to conduct experiments. 3  However, often the substances being experimented with are microscopic in suâ¦.
