How to convert percent to ppm

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
