  4. 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.

  5. 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.

    PPM and PPB are units used in atmospheric chemistry to describe the concentration of gases. PPM stands for parts of gas per million parts of air, and PPB is parts per billion. If that's not easy to imagine, try these examples: Part per million (ppm): 1 second in just under 2 weeks. 1 litre of water in a swimming pool. Part per billion (ppb):

  7. Parts per billion (ppb) is a unit of measurement used to express the concentration of one substance in a solution. It denotes one part of solute per billion parts of the total solution.

  8. Aug 24, 2019 · Related concentration units are parts per thousand (ppth), parts per million (ppm) and parts per billion (ppb). Parts per thousand is defined as follows: \[ppth\: =\: \frac{mass\: of\: solute}{mass\: of\: sample}\times 1000\]
