How to convert number in percent (%) to parts-per million (ppm).

## Percent to ppm conversion

1% = 1/100

1ppm = 1/1000000

So, one percent is equal to 10000 parts-per million:

1% = 10000ppm

So

*x*_{(ppm)} = 10000 ⋅ *x*_{(%)}

#### Example

Convert 1.7% to ppm:

*x*_{(ppm)} = 10000 ⋅ 1.7% = 17000ppm
