   What is a part per billion?

   • One part per billion is one part of solute per one billion parts solvent. PPB is a commonly used unit of concentration for very small values. The "parts per" notation is not part of the SI system of units. The notation describes dimensionless quantities. The ppb notation is most often seen in physics and engineering.

   What is ppm and ppb in chemistry?

   • 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.

   What are parts per million & trillion?

   • They are abbreviations for the words parts-per-million, parts-per-billion, and parts-per-trillion. These symbols have become commonplace in everyday use, in the media for example, as well as in scientific and technical contexts. If we regard them as units it is important to note that they are not part of the SI.

   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:

   How do you calculate ppm & ppb?

   • PPB = (Number of Parts of Solute / Number of Parts of Solution) x 1,000,000,000 For instance, if you have 5 parts of a solute in 2000 parts of a solution, the calculation would be: PPB = (5 / 2000) x 1,000,000,000 = 2,500,000 PPB Converting between PPM and PPB is relatively straightforward, as they are both based on parts per million.

   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.

   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 even numbers of atoms, as long as the units are the same (so that units cancel).

   What are Parts per Million (PPM) and Parts per Billion (PPB)? Parts per million (PPM) is a unit of measurement commonly used to express the concentration of a solute in a solution. It represents the number of parts of the solute per million parts of the solution.

   “Parts-per” notation is used, especially in science and engineering, to denote relative proportions in measured quantities; particularly in high-ratio (low value) proportions at the parts-per-million (ppm), parts-per-billion (ppb), and parts-per-trillion (ppt) level.
