The difference in elevation between points is called the rise. 002150 feet 3 feet. Percent slope 100 YX.
Calculated out this gives an angle percentage of 60.
1 As a ratio of the rise to the run for example 1 in 20 2 As an angle almost always in degrees 3 As a percentage called the grade which is the rise run 100. Riserun 2100 002 Thus if riserun 002 and the run is 150 the rise in feet is actually a drop. Angle Percentage 6 10 x 100. Percent Slope Formula The following formula is used to calculate the percentage of a slope of a line with respect to rise over run.
