How do i calculate percentage of slope based on angle.?

if my driveway has a 14 degree angle, what is the % of slope?How do i calculate percentage of slope based on angle.?
No trigonometry required for this one.



A 90 degree angle is a 100% slope (straight up) so you divide the angle you have by 90 and then multiply by 100 to get the percentage slope.



14 degrees / 90 degrees = 0.1555555... (the 5's keep repeating.)



0.1555555... * 100 = 15.55555...% slope.How do i calculate percentage of slope based on angle.?
