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 convert percent grade to slope?
how to convert slope into percent grade
What percent grade is a 3 to 1 slope?
It is a 300% slope!
What is the steeper slope 30 percent or 15 percent?
30% is steeper than 15% slope.
How do you figure percent as 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%.
What is the grade for 66 percent 99 percent?
66% is a D grade and 99% is an A grade.
