Nov 28, 2023 · The concept behind ppm is simple – it represents the number of parts of a substance per one million parts of a solution. The ppm measurement system gained widespread popularity in various fields, including chemistry, environmental science, and industry.
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. For example: mg/kg. One ppm is equal to 1/1000000 of the whole: 1ppm = 1/1000000 = 0.000001 = 1×10-6 . One ppm is equal to 0.0001%: 1ppm = 0.0001%

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.
The expression "1 ppm" means a given solute exists at a concentration of one part per million parts of the solution. These are two common ways to think about what the concentration "1 ppm" means: a) it is one-millionth of a gram per gram of sample solution. b) it is one gram of solute per million grams of sample solution.
Aug 3, 2018 · Parts per million (ppm) is a commonly used unit of concentration for small values. One part per million is one part of solute per one million parts solvent or 10-6. Parts per million and other "parts per" notations (e.g., parts per billion or parts per trillion) are dimensionless quantities with no units.
