Scientists commonly use units of parts per million (ppm) to describe the concentration of chemicals in solutions. A concentration of 1 ppm means there is one "part" of chemical in 1 million equivalent parts of the solution. Since there are 1 million milligrams (mg) in a kilogram (kg), th...
PPM or Parts Per Million is a unit used to describe very small concentrations of a substance in a larger solution. PPM means 1 per every 1,000,000 or 1/1,000,000.What is PPM in Science? PPM, meaning parts per million, is best used to describe the quality of performance or concentrat...

In air pollution literature ppm applied to a gas, always means parts per million by volume or by mole. These are identical for an ideal gas, and practically identical for most gases of air pollution interest at 1 atm. Another way of expressing this value is ppmv. [1]One part per million...
Keep in mind that ppm is a relative measurement and can be affected by various factors, such as temperature, pressure, and specific gravity. It's always essential to consider these factors when interpreting ppm values. Now you know what parts-per-million means!
