ppm is called 1000 liter water included 1 gm of material. So, 1ppm is called 1 liter water contained with 1 gm of material. If the yellow medicine 200 ~ 300 gm included in the 10 liter water, it is called 20 ppm ~ 30 ppm.  The consistency 1% is meant adding 1000 gm material into 100 liter water, also meant adding 10 gm material into 1 liter water.
