How to Calculate an Angle in Degrees using Rise over Run
The formula to calculate the slope of a line is often called rise over run. Rise is equal to the height of a line, and run is equal to the horizontal length of a line.
The rise over run formula for calculating a slope is rise divided by run.
rise/run
We can solve the angle of an incline by finding the rise and the run of a line. First, convert rise and run to the same units of measure.
Then, divide the rise by the run to find the decimal form.
Finally, get the inverse tangent of the decimal to find the angle in degrees.
Thus, the formula to convert rise over run to an angle in degrees is:
degrees = tan-1(rise/run)
For example, given a rise of 10′ and a run of 20′:
degrees = tan-1(10 ÷ 20)
degrees = tan-1(.5)
degrees = 26.57°
The slope or incline of a line or elevation can be expressed as a gradient(rise/run), angle in degrees, decimal, or percentage.
