To convert part per million (by weight) into miligrams in 8 oz. do the 
following:

One fluid oz.of CS equals about 30 grams.
8 oz. of CS is therefore 240 grams in which you have 20 ppm.
The grams of silver contained in your 8 oz,
20x240/1000000=0.0048 gr or 4.8 miligrams.
This asumes that the specific gravity of a ppm CS dispersion is 1.00.
Hope it hels

  hello 'yall,

  does anyone know how i could calculate the gram or milligram content of my cs?

  let's say, 8oz of 20ppm for instance.

  thanks,
  angel
