DPMO : Sigma Level Table

A Six Sigma conversion table is a tool for translating defect rates (defects per million opportunities or DPMO) into corresponding Sigma levels. There are a few key factors to know that will help you understand this tool better.

2025年2月3日 · How do you calculate Sigma to DPMO? Find out how to easily convert between units with our handy table and calculations in this short guide.

Defects per million opportunities (DPMO) is the number of defects in a sample divided by the total number of defect opportunities multiplied by 1 million. It is used for measuring the level of performance and gain of performance of a process. Use this DPMO Process Sigma table to find the equivalent process sigma metric and yield for a DPM.

Long Term Sigma / PPM / Cpk Table The conversion table below is similar to the one above but lets discuss the differences. It is very important to remember that DPMO and PPM may or may not be the same. Lets use an exaggerated example to illustrate a point.

Use this sigma calculator to easily calculate process sigma level, defects per million opportunities (DPMO, PPM), yield, rolled throughput yield (RTY), percent defects, percent defect units, as well as defects per million units (DPM).

Aus dem berechneten DPMP Wert wird aus der untenstehenden Tabelle der entsprechende Sigma Wert ermittelt. Die drei Qualitätskennzahlen DPMO, ppm und DPU ergeben zusammen ein umfassendes Bild der Prozessleistung – es ist durchaus …

The document shows tables with the relationship between sigma levels, defects per million opportunities (DPMO), yield percentages and defect rates both with and without a 1.5 sigma shift. The tables provide data on sigma levels from 1 to 6 and show that as sigma level increases, DPMO, defect rates and yield percentages improve.

Entdecken Sie den Wert von DPMO (Defektanzahl pro Millionen Möglichkeiten) als Instrument zur Messung und Verbesserung der Produktqualität, und erfahren Sie, wie Sie es nutzen können, um Ihre Prozesse in Richtung Six Sigma zu optimieren.
