   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 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.

   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?

   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).
