How is elevation difference calculated?

An easy-to-remember equation for finding change in elevation as a decimal is “rise over run,” meaning the rise (the change in vertical distance) divided by the run (the change in horizontal distance).

As an example, let’s say the rise is 2 and the run is 6.
