Is 6% a steep grade?
Driving down a highway you may see a road sign that reads “6% Grade” or “Steep Grade.” The grade of the road is, essentially, its slope. A six percent slope means that the road elevation changes 6 feet for every 100 feet of horizontal distance (Figure 1.3).
What is a 10% gradient?
It expresses the ratio of difference in altitude between two points on a slope to the horizontal distance between the points, multiplied by 100. For example a 10 percent slope means that, for every 100 feet of horizontal distance, the altitude changes by 10 feet: Facebook. Twitter.

Which is an example of a 0 percent grade?
For example, a flat surface can be referred to as a 0 percent grade or a 180-degree angle: there is no change in height as the road continues. (In mathematical terms, there is no rise over the run.)
Is it possible to have a 100 percent grade?
(In mathematical terms, there is no rise over the run.) A 100 percent grade would be equivalent to a 45-degree angle or, in other words, the rise would be equal to the run. It is also possible to have an infinite percent grade as that is defined as any amount of rise with no run at all.
