# Control Limit Calculator | UCL & LCL Calculator

Control charts monitor the quality of the elements. The center line in the control chart is the mean, the two horizontal line is the ucl and lcl. Find if the element is outside control limit using the ucl calculator. The statistical process control has the highest level of quality for a product in the ucl lcl calculator. Enter the control mean, standard deviation and the limits in the control limit calculator. The lower control limit (lcl) calculator finds the lower and upper limits of control.

Code to add this calci to your website  #### Formula:

Lower Limit Value = x - (l x s) Upper Limit Value = x - (- l x s) Where, x = Control Mean s = Control Standard Deviation l = Control Limit you Wish to Evaluate

### Example:

A process has a control mean of 10, a standard deviation of 20 and the control limit that the company wishes to find is 2. Find the upper and lower limit?

#### Solution:

Lower Limit:
w = 10 – (2 x 20)
= -30
Upper Limit:
u = 10 - (- 2 x 20)
= 50
