## 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-trillion(ppt)

1. Check definition
1 parts-per-million = 1/106 = 10-6
1 parts-per-trillion = 1/1012 = 10-12

2. we get:
1ppm = 1000000ppt

## Example

1. 1ppm = 1000000ppt

2. 2ppm = 2000000ppt

3. 5ppm = 5000000ppt

4. 0.1ppm = 100000ppt

5. 0.2ppm = 200000ppt

6. 10ppm = 10000000ppt
