Difference in height of two points in relation to their horizontal distance in percent. The angle is calculated with: arcus tangens x (height difference broken by distance). An upward slope is called a slope, a downward slope (the two terms are only linguistically different, there is no difference arithmetically). At a 30% gradient, the other point 100 meters (horizontally) away is 30 meters higher, resulting in an angle of 16.69 °. An inclination of 75% results in 36.87 °. An incline of 100% corresponds to an angle of 45 °, i.e. 100 meters horizontally and 100 meters vertically. Up to this inclination the use of Monorackbahnen (Monorail rack railways) possible, an incline of 200% corresponds to an angle of ~ 64 °. For angles of inclination just below 90 °, the slope grows to infinity. A slope of 90 ° corresponds to a vertical wall. Overhanging walls correspond to more than 90 °.
When specifying in percent (%), the inclination angle and slope are not proportional to each other. It is therefore not possible to convert angles and slopes with a final calculation (mathematical method to calculate the unknown fourth value from three given values of a ratio). The steepness of vineyards is usually given in percent. However, it is not uncommon for the values given to be incorrect due to incorrect conversion (in the case of very steep vineyards, the slope is often over 45 ° or 100%). Steep vineyards are favored by good (at best vertically incident) sunshine and usually produce better grape or wine qualities. In addition to the angle of inclination exposition (Direction of the sun) important. Important criterion for the Weinbauwürdigkeit of vineyards is a hillside with a good inclination.
