Knowledge of converter
In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are ppm (parts-per-million, 10−6), ppb (parts-per-billion, 10−9), ppt (parts-per-trillion, 10−12) and ppq (parts-per-quadrillion, 10−15). This notation is not part of the SI system and its meaning is ambiguous.
How to convert parts-per-million(ppm) to parts-per-billion(ppb)
- Check definition
1 parts-per billion = 1/109 = 10-9
1 parts-per-million = 1/106 = 10-6 - we get:
1ppm = 1000ppb
Example
- 1ppm = 1000ppb
- 5ppm = 5000ppb
- 10ppm = 10000ppb
- 0.1ppm = 100ppb
- 0.5ppm = 500ppb
