Enter the grid scale factor and the elevation factor into the Calculator. The calculator will evaluate the Combined Scale Factor.

## Combined Scale Factor Formula

CSF = GSF * EF

Variables:

- CSF is the Combined Scale Factor ()
- GSF is the grid scale factor
- EF is the elevation factor

To calculate Combined Scale Factor, multiply the grid scale factor by the elevation factor.

## How to Calculate Combined Scale Factor?

The following steps outline how to calculate the Combined Scale Factor.

- First, determine the grid scale factor.
- Next, determine the elevation factor.
- Next, gather the formula from above = CSF = GSF * EF.
- Finally, calculate the Combined Scale 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.

grid scale factor = 1.34

elevation factor = 2.87
