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.
One milligram in a kg is 1ppm (by mass). One liter (L) of pure water at 4ÂºC and 1standard atmosphere pressureweighs exactly 1 kg, so 1 mg/Lis 1 ppm. Another way to sayit is a liter of water weighs1,000 grams or 1 million mil-ligrams.Therefore, 1 mg in 1liter is l mg in 1 million mil-ligrams or 1 part per million. common mistake is report-ing a concentration as ppmwhen it is really ppb. This is abig difference, such as the differ-ence between $1 and $1,000. As a ppm is equal to mg/L, thenppb is equal to microgram perliter (Âµg/L).
