   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.

   Definition. Parts per million (ppm) and parts per billion (ppb) show a relationship between two quanti-ties that use the same units. A part per million could be one drop per one million drops, one gram per one million grams, etc. By definition, one ppm = 1,000 ppb.

   An even smaller concentration measurement, used for methane (CH4) is parts per billion (ppb). One ppb is one part in 1 billion. One drop of ink in one of the largest tanker trucks used to haul gasoline would be an ink concentration of 1 ppb.

   Parts per billion ("ppb") denotes one particle of a given substance for every 999,999,999 other particles. This is roughly equivalent to one drop of ink in a lane of a public swimming pool, or one second per 32 years.

   Mar 5, 2019 · PPB stands for parts 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.

8. People also ask

   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.

   • An even smaller concentration measurement, used for methane (CH4) is parts per billion (ppb). One ppb is one part in 1 billion. One drop of ink in one of the largest tanker trucks used to haul gasoline would be an ink concentration of 1 ppb. Because a ppb is a thousand times smaller than a ppm, other analogies would be:
