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.
