   Very low solute concentrations are often expressed using appropriately small units such as parts per million (ppm) or parts per billion (ppb). Like percentage (“part per hundred”) units, ppm and ppb may be defined in terms of masses, volumes, or mixed mass-volume units.

   Definition. Parts per million (ppm) and parts per billion (ppb) show a relationship between two quanti-ties that use the same units. A part per million could be one drop per one million drops, one gram per one million grams, etc. By definition, one ppm = 1,000 ppb.

   In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.

   In the case of ppb, the same relationship exists: 1 part material per 1 billion parts of a gas, liquid or solid. An easy way to think of ppm is to visualize putting four drops of ink in a 55-gallon barrel of water and mixing it thoroughly. This procedure would produce an ink concentration of 1 ppm.

   What is the difference between pPb and PPM?

   • An even smaller concentration measurement, used for methane (CH4) is parts per billion (ppb). One ppb is one part in 1 billion. One drop of ink in one of the largest tanker trucks used to haul gasoline would be an ink concentration of 1 ppb. Because a ppb is a thousand times smaller than a ppm, other analogies would be:

   What does a billion and a trillion mean?

   • A particular problem arises in the meaning of a billion and a trillion: the usual meaning of these words today is 10 9 and 10 12 respectively, but there are still a few countries (notably Scandinavia) where a billion and a trillion are taken to mean 10 12 and 10 18 respectively, with corresponding changes to the meaning of ppb and ppt.

   Definition. Parts per billion (ppb) is a unit of measurement used to express the concentration of a substance in a solution or mixture. It indicates how many parts of a substance are present in one billion parts of the total mixture, making it a vital metric for assessing trace amounts of gases and pollutants in the atmosphere.
