  4. 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.

  5. 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.

  6. Mar 5, 2019 · 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.
