Understand how to accurately calculate the elevation grade or slope percentage between two points. This online calculator simplifies complex geometry, making it easy to determine the steepness of roads, trails, or land for construction, engineering, or hiking. Input your starting and ending elevations and the horizontal distance to instantly get the grade percentage.
Formula:
The formula for calculating elevation grade (slope percentage) is:
Grade (%) = ((Elevation2 - Elevation1) / Horizontal Distance) × 100%
Where:
- Elevation1: The starting elevation of the first point.
- Elevation2: The ending elevation of the second point.
- Horizontal Distance: The horizontal (planimetric) distance between the two points.
Note: Ensure all units (Elevation and Horizontal Distance) are consistent for accurate results.
