How to Convert Rise Over Run to Percent Slope
Percent slope (grade) is the rise divided by the run, multiplied by 100.
Slope % = (Rise / Run) × 100
For example, a road that rises 5 meters over 100 meters of horizontal distance:
(5 / 100) × 100 = 5% grade
Example
Rise = 3, Run = 12. What is the slope?
(3 / 12) × 100 = 25%
