How to convert ppm to percent

ppm to percent conversion

1% = 1/100

1ppm = 1/1000000

So one parts-per million is equal to 0.0001 percent:

1ppm = 0.0001%

So to convert from ppm to percent, divide the ppm by 10000:

x(%) = x(ppm) / 10000

Convert 300ppm to percent:

x(%) = 300ppm / 10000 = 0.03%
