What is the formula for calculating slope?

The formula for calculating slope is correctly defined as the difference in elevation over distance, and when you multiply that result by 100, you express the slope as a percentage. This is an important concept, especially in contexts like on-site sewage facilities, where understanding the incline of land can affect drainage, installation, and overall system performance.

Slope essentially represents the steepness or degree of incline of a surface. By dividing the difference in elevation (the vertical change) by the distance (the horizontal change), you get a ratio. When this ratio is then multiplied by 100, it provides a percentage that is easier to interpret and apply in practical scenarios. A slope of 5% indicates that for every 100 units of horizontal distance, the elevation changes by 5 units. This measurement is crucial when planning and implementing sewage facilities, as it helps ensure proper drainage and prevents issues related to insufficient fall or excessive slope, contributing to the efficiency and safety of the sewage system.
