Diff between 2% and 2 Degrees on 12m?

Question

On a design of a road, the faal of the road is 2% or 2 degree, I wane know what is the diff between them

Answer 1

slope av rode...kommonly kalled the grade

in the old daes em yuze persent...

1% meen rise=1 ft for 100 ft run...(run=horizontal distans)

so 2% go up 2 in 100

for 12 meter leng...0.02*12=0.24 meter

###### 2 degrees: rise=120meters* tangent(2 deg)

tan(2 deg)=0.03492

12*0.03492=0.41904923
