ISO cleanliness code to PPM

halMember

Can an ISO cleanliness code be converted to ppm? Cold rolling mill coolant system debris (ash) is reported in ppm. These systems range from 10,000 to 25,000 gallons in size. We often check the system filtration by particle counts at 4,6,14 um. What is the correlation between the two and can it be converted?
