- 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 the abbreviation PPB stand for? Meaning: parts per billion.
Parts per billion (ppb) is a unit of measurement used to express the concentration of a substance in a solution or mixture. It indicates how many parts of a substance are present in one billion parts of the total mixture, making it a vital metric for assessing trace amounts of gases and pollutants in the atmosphere.
Use this concentration unit conversion tool to easily convert between parts per million (ppm), parts per billion (ppb), and parts per trillion (ppt). Essential for accurate and efficient concentration conversions in chemistry, environmental science, pharmaceuticals, and health safety.

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.
Parts per billion. A means of expressing minute concentrations, often of an element, compound, or particle that contaminates soil, water, air, or blood. The expression may be on either a mass or a volume basis, or a combination of the two, such as micrograms of a chemical per kilogram of soil, or micrograms of chemical per liter of water.
