   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 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 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 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.

   Why are ppm and ppb not available for dimensionless quantities?

   • However they are not available for dimensionless quantities, because there is no unit to which they may be prefixed. The symbols ppm, ppb, and ppt are used to escape this problem. They are best thought of as non-SI units for dimensionless quantities with the meanings 10 −6, 10 −9, and 10 −12 respectively.

   Jan 30, 2023 · However, instead of using the recipe's "1 part per ten" amount, chemists often use parts per million, parts per billion or parts per trillion to describe dilute concentrations. Parts per Million : A concentration of a solution that contained 1 g solute and 1000000 mL solution (same as 1 mg solute and 1 L solution) would create a very small ...
