Calculating %, ppm, ppb, and ppt

2012-2-6 · Percent, ppm, ppb, and ppt page 2 Revised by D Lingner, 11/23/2009 In chemistry, it's more like this: you have a 150 gram sample and you figure out that it contains 0.00006 grams of gold. To express this in %, ppm, and ppb, you do the same sort of calculation as above and it always involves the part/whole ratio: 0.00006 g

### PPM (Parts Per Million) -Defective Rate - Xmultiple

2015-6-29 · To calculate: For example, if you had 25 pieces defective in a shipment of 1,000 pieces. 25/1000= .025 or 2.5% defective. .025 X 1,000,000 = 25,000 PPM. Use the PPM Calculator: How to calculate PPM is best explained in an example.

Process Capability (Cp, Cpk) and Process Performance

2021-4-17 · C pk measures how close you are to your target and how consistent you are to around your average performance. A person may be performing with minimum variation, but he can be away from his target towards one of the specification limit, which indicates lower C pk, whereas C p will be high. On the other hand, a person may be on average exactly at the target, but the variation in performance How do you calculate rejections PPM in an injection molding production unit

What is PPM and How do I calculate it?

2017-8-24 · Definition: One PPM means one (defect or event) in a million or 1/1,000,000. There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to 0.1% or 1,000 PPM. Now the rate for most automotive components is targeted at 25 PPM or 0.0025%
