You just have to substitute values of slope and vertical distance in formula and get value of horizontal distance. Similarly, any one of them can be found if other two are given. For instance, if you have a slope given in Percentage as 10 % and a vertical distance of 50 feet, then equation will look like:
Thus the angle in the diagram above can be expressed as 45Ë or 1.0 (ratio) or 100%. To measure slope inclination in the field we use a clinometer (Suunto is the most common make). This device provides measures in both degrees and percent. 21.2 m / cos [ 32 ]. = 25 m. Measures of slope in degrees are useful for converting slope distance to horizontal distance, but percent is easier to use to calculate change in elevation. Remember that tan is slope is expressed as a ratio ...
