Concentration: I prefer to use CS for ingesting and for topical use at a concentration of 48-50 ppm. Using a 2-gallon container and 2“x 6“ electrodes over 48 hours, I get 1 ppm per hour. For the highest quality smallest almost monoatomic nanoparticles, turn the nanometer size knob to the lowest level.
Conversion table percent to ppm
| Percent (%) | ppm |
| 0.0001% | 1 ppm |
| 0.001% | 10 ppm |
| 0.01% | 100 ppm |
| 0.1% | 1000 ppm |
| 1% | 10000 ppm |
1 percent = 10000 ppm
One ppm is equivalent to 1 milligram per liter of water (mg/l) or 1 microgram per ml.
1ppm = 0.0001% So to convert from ppm to percent, divide the ppm by 10000.
Our 50 ppm colloidal silver contains 50 micrograms per ml so that a minimum daily requirement of silver or copper would be 10 ml which = one-third of an ounce = 2 teaspoonfuls.
One tablespoonful = 0.5 ounces = 15 ml
