Measuring grade on hills

---My little gauge indicates my rig is at a 10-degree attitude while climbing my driveway. That's about a 11% grade. Pretty steep for me to walk.

A 10-degree slope is close to an 18% grade.
Hope that doesn't make it seem even steeper for you to walk. :)

The percent gradient for slopes from 1 to 10 degrees are given below:

Slope in degrees in column 1
Gradient in percentage in column 2

1 ____ 1.75%
2 ____ 3.49%
3 ____ 5.24%
4 ____ 6.99%
5 ____ 8.75%
6 ____ 10.51%
7 ____ 12.28%
8 ____ 14.05%
9 ____ 15.84%
10 ____ 17.63%


For small slopes, to convert degrees to gradient,

multiply slope, in degrees, by 100 times pi (3.1416) divided by 180

or, approximately 1.75% per degree.

The actual ratio increases as slope increases. At a slope of 45 degrees, which is a gradient of 100%, the ratio is 2.22% per degree.
