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 ppm are in 1.7%. x (ppm) = 10000 ⋅ 1.7% = 17000ppm PPM means "Parts per million" MG/L means "Milligrams per liter" Note: PPM and MG/L are the same thing.
