2019-03-28 ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000. ppm is dimensionless quantity, a ratio of 2 quantities of the same unit. One part per million would mean that there is one gram of the pollutant in every one million grams of air.

Weight of substance added to one unit volume of water to give one part per million (ppm) 1 ppm = 2.72 pounds per acre-foot = 1,233 grams per acre-foot Thus, every Cpk value corresponds to a percent defective rate, which may be expressed in parts per million, or ppm. Table 1 shows some Cpk values and their equivalent ppm rates. In the semiconductor industry, the Cpk goal for a process is normally set at 1.67 , although a Cpk of 1.33 is still considered acceptable.

There are two reasons for this. First, sp2 hybridized carobs are more electronegative than sp3 carbons since they have more s character (33% vs 25% s). Seeing ppm or mg/L on a lab report means the same thing.

What does PPM stand for?
Björn lundberg

One parts per million is equal to 0.998859 milligrams per liter. The unit PPM can be converted into Mg/l by multiplying it with 0.998859. Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution.

APPENDIX 1. Small units of mass and their abbreviations: Milligram ( mg): The prefix “milli-” means “1/1000 of” (one thousandth of).
