كيفية تحويل Ppm إلى Mg / Kg. علم 2021. يمكنك استخدام كلا الجزأين لكل مليون (جزء في المليون) ومليغرام لكل كيلوغرام (ملغم / كلغ) لوصف تركيز مركب واحد مشتت في 

ppm↔mg/kg 1 ppm = 1 mg/kg. ppm↔mg/g 1 mg/g = 1000 ppm.

Parts Per Million (ppm) 1 milligram/kilogram (mg/kg) = 1 ppm 1 milligram/liter (mg/l) = 1 ppm 1 microgram/gram (µg/g) = 1 ppm 0.0001 % = 1 ppm 1 ppm Analogies 1 inch in 16 miles 1 minute in two years 1 second in 11.5 days 1 car in bumper -to-bumper traffic from Cleveland to San Francisco 8.34 pounds/million gallons

1 ppm is 1000 times Smaller than 1 g/L. 2020-04-05 · Therefore, 1 mg/kg is the same as 1 ppm because 1 milligram is equal to 0.001 grams while 1 kilogram is equal to 1,000 grams. So, if you divide 0.001 by 1,000, then the result is 0.000001, which is a millionth of a gram, making it the same as 1 part per million. This logic only works for mass conversions. 2011-08-28 · ppm is the number of units of solute per million units of solution, i.e. how many grams of XYZ in every million grams of a solution. You can also think of it in terms of how many milligrams of solute per kilogram of solvent (since there are a million mg in a kg).
