Calculate the concentration of a substance in parts per billion (ppb) based on the mass of the solute and solution.
Learn how to use the Parts Per Billion Calculator and its working principles
Parts per billion (ppb) is a unit of measurement used to describe very dilute concentrations. It represents one part in one billion parts of a whole.
For example, if you have 1 milligram of solute in 1 kilogram of solution, the concentration would be 1 ppb.
The ppb unit is commonly used in environmental science to measure trace amounts of pollutants in water and air. It is also used in other fields such as chemistry, physics, and engineering.
Suppose you have 0.5 mg of a substance in 100 kg of water. The calculation would be:
ppb = (0.5 mg / 100 kg) × 1,000,000,000 = 5,000,000 ppb
