Conversion Of mg/kg Into ppm
posted by Greg:Edward,
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.
1 mg = 0.001 grams
1 kg = 1,000 grams
0.001 / 1,000 = 1/1,000,000 = one ppm.
Conversion From Gram To Ppm

No, You Need To Know The Atomic Weight Of The Substance
posted by Dave:No, if you want to know how much lead is in water (for example), you cannot take mg/kg and call that ppm, because lead had a different atomic weight than water!!
