"Percent Slope" is a representation that uses the ratio between the rise and run to describe the triangle formed. "Degree slope" is the measure of the angle formed. You can simply take the percent and divide by 100 to get back to the real ratio and then take the inverse tan of that number to give you the degrees of slope.

15%ramp is a rise of 15/100 = 0.15 slope angle is inverse tangent of this, or 8.53 degrees
30% is steeper than 15% slope.
It is a 300% slope!

To convert 'D' degrees into a percent slope, you could use the Excel formula:= 100 * TAN ( D / 57.296 )
Divide the degree by (360/100) = 3.6
To convert .25 inch per foot into degrees or percent slope, you first need to determine the rise over the run. In this case, .25 inch per foot is equivalent to a rise of .25 inches for every 12 inches of horizontal distance (1 foot). To convert this into degrees, you can use the arctangent function: arctan(.25/12) ≈ 1.19 degrees. To convert this into percent slope, you can use the formula: percent slope = (rise / run) x 100. In this case, it would be (.25/12) x 100 ≈ 2.08% slope.
-- Measure how far the slope rises in 100-ft of horizontal distance.-- That number is the percent of slope, or the "grade".-- If you want the angle of the slope, divide the number by 100, and look upthe "arctangent" of the answer in a table or on a calculator.
The slope for a 45 degree slope triangle is 1/1 because the slope triangle is an isosceles right triangle.
Let m be the slope in percent and theta be the angle in question. tan (theta) = m/100 theta = arctan (m/100) To verify the result, we know the following: tan 0 = 0 tan (45 degrees) = 1 = 100% tan (90 degrees) = infinity For example, if 0 < m < 100%, then 0 < theta < 45 degrees.
