ppm to percent?
by Monessen on 10/28/05 at 11:07:00
I need to find out how to convert CO emissions from parts per million to percent volume. I'm sure there is more info required to do this so please let me know what else you may need. Any help is greatly appreciated.

1 PPM is 1/1,000,000 = 0.000001 which would be 0.0001%
So you would divide by 10,000
10 ppm = 10/10000 = 0.001%
It wont matter what the substance is in this case.
