C(ppm) = 1000000 × msolute / (msolution + msolute) The PPM Numerical Computation is comprised of 40 multiple choice items and has a 6 minute time limit. The Numerical Computation Test is part of the Power and Performance Measures (PPM) series of tests. What the PPM Numerical Computation Test Measures Multiplying 0.000001 by 1,000,000 gives a result of 1ppm. Here is a video discussing this type of calculation.
