   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.

   How much is 1 ppb in G/L?

   • 1 ppb is equivalent to $1 \mu g/L$ when measuring concentrations in water. PPB is often used for measuring extremely low concentrations of pollutants or contaminants. In chemical solutions, ppb can be converted to other units like ppm (parts per million) by understanding the relationship: 1 ppm = 1000 ppb.

   How do you calculate parts per million?

   • Note that for each “parts per” calculation, the ratio definition is the same, and the power of 10 used is the same as in the name (i.e. “parts per million” is the mass ratio times one million, “parts per billion” times one billion, etc). Knowing this, how would you calculate another common unit, parts per thousand?

   How do you convert ppb to ppm?

   • In chemical solutions, ppb can be converted to other units like ppm (parts per million) by understanding the relationship: 1 ppm = 1000 ppb. The sensitivity required for detecting substances at the ppb level typically necessitates sophisticated analytical techniques such as mass spectrometry or chromatography.

   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.

   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 even numbers of atoms, as long as the units are the same (so that units cancel).
