Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example: find how many percent are in 300ppm. x (%) = 300ppm / 10000 = 0.03%. ppm to percent conversion table
