PPM is an acronym for _____________________________.

• A. Pounds per meter
• B. Parts per million
• C. Proportion per mille
• D. Parts per meg

Answer: (B)

PPM is a way to express very small concentrations as a ratio of one part in a million parts. It means there is one unit of the substance for every 1,000,000 units of the whole, which makes it ideal for describing trace amounts or impurities. In practical terms, this is commonly used to report contaminants, residual solvents, or potency levels in cannabis products, where tiny amounts matter for safety and quality. The other options describe different ideas: pounds per meter is a mass per length measure, not concentration; per mille means one part in a thousand, which is a coarser scale than a million; and parts per meg is another phrase that can be used to mean the same ratio but is far less common in everyday practice, so the standard term typically used is parts per million.
