   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.

   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.

   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.

   Jan 30, 2023 · Parts per Trillion: Just like ppb, the idea behind parts per trillion (ppt) is similar to that of ppm. However, 1 ppt is 1000-fold more dilute than 1 ppb and 1000000-fold more dilute than 1 ppm. \[\text{1 ppt} = \dfrac{ \text{1 ng Solute}}{\text{1 L Solution}}\]

   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 the difference between pPb and PPM?

   • 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:

   How do you calculate ppm / ppb?

   • 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. Ppm/ppb can be measured by weight (ppmw/ppbw) or by volume (ppmv/ppbv), depending on what’s being measured. Some documents will tell you if it’s weight or volume, other times you will need to figure it out yourself.
