# Defects Per Unit Calculator

Defect Per Unit (DPU) refers to the average number of defects in a given sample product. It is different from the traditional measurement of yield. It is a ratio of the number of defects over the number of units tested. DPU is one of the Six Sigma defects metrics. It is an estimation of how well the product or process performs based on the total number of defects. Use our online Defects per unit calculator to do DPU calculation six sigma based on observed defects and total units.

#### Formula:

u = (o / i)
**Where,**
u = Defects Per Unit
o = Number of Defects Observed
i = Number of Units Inspected
### Example:

Calculate the defects per unit for the observed number of defects of 50 and the inspected number of units of 120.

#### Solution:

u = (50 / 120)

= 0.4167
