## 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)

1. Check definition
1 parts-per billion = 1/109 = 10-9
1 parts-per-million = 1/106 = 10-6

2. we get:
1ppm = 1000ppb

## Example

1. 1ppm = 1000ppb

2. 5ppm = 5000ppb

3. 10ppm = 10000ppb

4. 0.1ppm = 100ppb

5. 0.5ppm = 500ppb
