U = number of Units in the sample. O = Opportunities per Unit. Then DPMO = 1,000,000 X D / ( U X O ) In our example, if there had been 7 defects (3 bearings for diameter and weight; 1 for roundness) out of 2,000 bearings, the calculation would be 1,000,000 X 7 / (2,000 X 4) = 7,000,000/8,000 = 875.

WebMar 9, 2024 · So this is basically “parts per part,” meaning that for one part solution you have 0.0002 parts salt. But of course, having this many decimal points isn’t exactly convenient, so to convert to PPM you multiply by 1,000,000 = 10 6, giving: 0.0002 × 10 6 = 220 PPM. The general approach works for volume calculations, too. WebNov 9, 2024 · The relationship between process capability and ppm defective is, I think, easier to explain by using Cp.
