Relationship between PPM and Molarity and Normality. PPM = M x M.Wt x 1000. PPM = N x Eq.Wt x 1000. Converting weight/volume (w/v) concentrations to ppm. ppm = 1g/m3 = 1mg/L = 1μg/mL. 1. A solution has a concentration of 1.25g/L. What is its concentration in ppm? Convert the mass in grams to a mass in milligrams: 1.25g = 1.25 x 1000mg = 1250mg
