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.
For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l). A measurement of 6 mg/L is the same as 6 ppm or 6,000 ppb, which is equal to 6,000 ug/L. A way to visualize one part per billion (ppb) in water is to think of it as one drop in one billion drops of water or about one drop of water in a swimming pool. One part per million is about 1 cup of water in a swimming pool.
