Enter the center-to-center distance and the sum of the ellipses’ radii into the Calculator. The calculator will evaluate the Separation Factor.

## Separation Factor Formula

SF = CCD / SER

Variables:

- SF is the Separation Factor ()
- CCD is the center-to-center distance
- SER is the sum of the ellipses’ radii

To calculate Separation Factor, divide the center-to-center distance by the sum of the ellipses’ radii.

## How to Calculate Separation Factor?

The following steps outline how to calculate the Separation Factor.

- First, determine the center-to-center distance.
- Next, determine the sum of the ellipses’ radii.
- Next, gather the formula from above = SF = CCD / SER.
- Finally, calculate the Separation Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

center to center distance = 16

sum of the ellipses radii = 40
