1. When is the term PPM used?
PPM has commonly been used in science and chemistry, and more recently in quality and continuous improvement. In science, it might be the number of contaminants per unit volume of liquid. Any ratio of units can be converted to PPM by multiplying the ratio by 1,000,000.
2. Can you give some examples of PPM?
It could be one inch in 16 miles or 1 second in 12 days.
3. Why would we use PPM?
It is a simply calculated unitless measurement that can be easily used to compare things. For example, if one lake has 25 parts of contaminant per million gallons, and another has 225 parts of contaminant per million gallons, you would say the second lake is more polluted.
