One part per billion ( ppb) denotes one part per 1,000,000,000 (10 9) parts, and a value of 10 −9. This is equivalent to about three seconds out of a century. One part per trillion ( ppt) denotes one part per 1,000,000,000,000 (10 12) parts, and a value of 10 −12.
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.
Parts per million and parts per billion may be converted from one to the other using this relationship: 1 part per million = 1,000 parts per billion. For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l).
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. The "parts per" notation is not part of the SI system of units. The notation describes dimensionless quantities.
This is a conversion calculator that is used to convert the numbers in parts-per-billion (PPB) to parts-per-million (PPM). It comes with a blank text field where you enter the value to be converted toparts-per-billion. Press the ‘Convert button to initiate the conversion from PPB to PPM.

Jan 30, 2023 · Parts per Million: A concentration of a solution that contained 1 g solute and 1000000 mL solution (same as 1 mg solute and 1 L solution) would create a very small percentage concentration. Because a solution like this would be so dilute, the density of the solution is well approximated by the density of the solvent; for water that is 1 g/mL ...
