Grade is usually expressed as a percentage, but this is easily converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for ...
Worked by adhesion between 1878 and 2001, currently out of service. 1 in 22. (4.5%) Balsam Mountain Grade. Balsam N.C. Balsam Mountain, home of highest railroad station east of the Rockies; average grade about 4.0%, max 4.5%. 1 of 2 grades on southern railways former Murphy branch that are +4% grade.
Drainage gradient (DG) is a term in road design, defined as the combined slope due to road surface cross slope (CS) and longitudinal slope (hilliness). Although the term may not be used, the concept is also used in roof design and landscape architecture . If the drainage gradient is too low, rain and melt water drainage will be insufficient.

The profile is the vertical aspect of the road, including crest and sag curves, and the straight grade lines connecting them. The cross section shows the position and number of vehicle and bicycle lanes and sidewalks, along with their cross slope or banking. Cross sections also show drainage features, pavement structure and other items outside ...
Ruling gradient. The term ruling grade is usually used as a synonym for "steepest climb" between two points on a railroad. More simply, the steepest grade to be climbed dictates how powerful the motive power (or how light the train) must be in order for the run to be made without assistance. Even if 99% of the line could be run with a low ...
Canton Avenue is a street in Pittsburgh 's Beechview neighborhood which is the steepest officially recorded public street in the United States. [ 1][ 2][ 3] Canton Avenue is 630 ft (190 m) long (the hill is about 213 feet long) and is claimed to include a 37% grade 21 feet (6.4 m) long.

As "percent" it is used to describe the grade or slope, the steepness of a road or railway, formula for which is 100 × rise / run which could also be expressed as the tangent of the angle of inclination times 100. This is the ratio of distances a vehicle would advance vertically and horizontally, respectively, when going up- or ...
