## What is Six Sigma calculation formula?

Defects per million opportunities (DPMO) Six-Sigma is determined by evaluating the DPMO, Multiply the DPO by one million.

DPMO= 0.33333 X 106 or 33,333.

Process Sigma Once you have determined the DPMO, you can now use a Six Sigma table to find the process sigma..

## How do you calculate ppm in Six Sigma?

To calculate DPMO, you need to know the total number of defect opportunities. For example, a form contains 15 fields of information. If 10 forms are sampled and 26 defects are found in the sample, the DPMO is: Parts per Million Defective (PPM) – the number of defective units in one million units.

## What percentage is 6 Sigma?

99.99966%A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects.

## How do you calculate ppm rejection?

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.

## What is the formula of PPM?

PPM = parts per million One thousanth of a gram is one milligram and 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter. PPM is derived from the fact that the density of water is taken as 1kg/L = 1,000,000 mg/L, and 1mg/L is 1mg/1,000,000mg or one part in one million.
