PPM vs. PPMV: Know the Difference
By Shumaila Saeed || Published on February 10, 2024
PPM (parts per million) measures the concentration of one substance within a million parts of another. PPMV (parts per million by volume) expresses gas concentration as volume per million volumes of air.
Key Differences
PPM, standing for parts per million, is a unit of measurement used to express concentrations of substances. PPMV, or parts per million by volume, is specifically used for gases, referring to the volume of a gas per million volumes of air.

In PPM, the concentration is expressed without specifying the substance's state, making it versatile for solids, liquids, or gases. Conversely, PPMV explicitly denotes the measurement of a gas's volume relative to the total volume, ideal for atmospheric studies.

PPM is often used in chemistry and environmental science to denote very low concentrations. PPMV, however, is most relevant in contexts like atmospheric chemistry, where gas volume ratios are crucial.

The use of PPM allows for a broad application across various scientific disciplines, while PPMV's usage is more niche, focusing on gaseous substances in environments like the atmosphere or industrial processes.

PPM can be used to describe concentrations in terms of mass, volume, or number, depending on the context. PPMV, being specific to volume, is limited to contexts where the volume of a substance is the key factor.
