Learn how to define and convert ppm and ppb units for very low solute concentrations in water and other solutions. See examples of how to use these units to report pollutants and contaminants in tap water.
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.
Related concentration units are parts per thousand (ppth), parts per million (ppm) and parts per billion (ppb). Parts per thousand is defined as follows: \[ppth\: =\: \frac{mass\: of\: solute}{mass\: of\: sample}\times 1000\]

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 ...
Mar 5, 2019 · PPB or parts per billion is a unit of concentration for very dilute solutions. Learn how to use the abbreviation in science, particularly chemistry, and see an example of its application.
Learn what parts per billion (ppb) means and how it is used to measure contaminants in different media. Find out the conversion factors and the difference between ppb and µg/l.
