sigma represents standard deviation. In a normal distribution, +/- 1 sigma from the mean, for instance, corresponds to approximately 67% of the area under the normal distribution. +/- 2 sigma corrresponds to 95% of the area and +/- 3 sigma from the mean corresponds to 99% of the area under a normal distribution. The area that is covered under +/- six sigma from the mean corresponds to nearly 100% -- that is, the part of the area NOT under that +/- 6 sigma is in the 10^-15 range or 1/1,000,000,000,000,000.
The six sigma name borrows from this to suggest that the method gives this degree of certainty: that in 999,999,999,999,999 in 1,000,000,000,000,000 cases the result will be predictable. It does nothing, however, to explain how an agricultural process management methodology applies to other fields.

What is the percent equivalent of 6 sigma?

What is the sigma standard?
The sigma standard, often referred to in the context of Six Sigma, is a statistical measure that quantifies process variation and performance. It indicates how many standard deviations (sigma) a process's output is from the mean, with higher sigma levels representing fewer defects and greater quality. In Six Sigma methodology, the goal is to achieve a 6-sigma level, which corresponds to only 3.4 defects per million opportunities, reflecting near-perfect process performance. This standard is widely used in quality management and process improvement initiatives.
What is the difference between 3 sigma and six sigma?
3 Sigma is 66800 defects per million pieces 6 Sigma is 3-4 defects per million pieces You can check out the number of defective pieces per million & the % accuracy for all Sigma levels in the six sigma conversion chart in the related links section

What is the sigma for 111111 defects per million?
To calculate the sigma level for 111,111 defects per million opportunities (DPMO), you first convert the DPMO to a proportion by dividing by 1,000,000, resulting in 0.11111. The corresponding sigma level for this defect rate is approximately 2.3 sigma, indicating that the process is not very capable and experiences a high rate of defects. In Six Sigma terms, processes are typically considered acceptable at 3.4 DPMO, which is around 6 sigma.
