1. Determine the height difference (a) between the start and end of the slope by subtracting the starting height from the final height (if it is a downhill slope the difference will be a negative number)
2. Determine the horizontal distance (b) between the starting point and the final point. If you only know the actual linear distance (c) along the slope, you can figure the horizontal distance using the Pythagorean Theorem: a2+b2=c2. For example, if the linear distance (c) along the slope from start to finish is 1000 feet, and the height difference (a) is 75 feet, then using the theorem you would have 752+b2=10002or 5625+b2=1000000. Your horizontal distance (b) would therefore be b2=994375 or b=997.2 feet
3. Divide the height difference (a) by the horizontal distance (b) and multiply by 100. This gives you the grade of the slope in percent. In the example it would be 75 ÷ 997.2 × 100 = 7.5% grade
how to convert slope into percent grade
It is a 300% slope!
30% is steeper than 15% slope.
Your question is a bit confusing. I can show slope as a fraction, decimal number or percent. A slope of a line from two points is the change in Y (delta Y) divided by the change in X (delta X). If my change in Y = -20, and my change in X is 100 (let's say I lost 20 pounds in 100 days), the slope is -20/100 or -0.20, which is the same as -20%.
66% is a D grade and 99% is an A grade.

maximum slope is 1 in 12 = 8.33 in 100 = 8.33 % grade

a forester uses them daily to quickly determine a tree's height, or percent grade on slope
80 percent would be an A and 38 percent you failed so the grade dont really matter
If there was only one assignment, your grade in the class is the grade received on that assignment.
-- 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.
When determining the measurement of slope on a road, the equations are for grade (gradient). The formula is grade = (rise ÷ slope length) * 100
