DPPM also termed as Defect Parts Per Million is a six sigma metric used in manufacturing in order to estimate the entire production load. Use this online calculator, to find the DPM and process sigma metrics based on the number of defects.
In a total of 500 units, 5 objects were rejected for some reasons. Hence,
DPPM = (5 / 500 ) x 1000000
= (1/100) x 1000000
