The Elevation Grade Calculator helps you calculate the grade or slope of a surface based on the vertical change (elevation difference) and horizontal distance. This tool is particularly useful for applications in construction, engineering, transportation, and landscape design, where understanding the slope of a surface is crucial for planning and analysis.

This calculator requires two inputs:

1. Vertical Change (mm): The vertical distance or elevation difference between two points. This is the change in height (measured in millimeters) between the starting and ending points.

2. Horizontal Distance (mm): The horizontal distance between the two points, measured in millimeters. This represents how far apart the points are along the horizontal plane.

The grade or slope is typically expressed as a percentage and is calculated using the following formula:

- Vertical Change is the height difference between two points (in millimeters).

- Horizontal Distance is the horizontal distance between the same two points (in millimeters).

- The result gives you the slope or elevation grade as a percentage (%), which represents how steep the surface is.

If you have a vertical change of 100 mm and a horizontal distance of 2000 mm, the calculation would be:

So, the surface has a 5% grade (meaning it rises 5 millimeters for every 100 millimeters of horizontal distance).

- Simple and Fast: Instantly calculate the slope or grade based on vertical change and horizontal distance.

- Useful for Various Applications: Ideal for construction, road design, land surveying, and any field where understanding the slope or grade of a surface is important.

- Expressed as a Percentage: The result is a percentage that is easy to interpret (e.g., a 5% grade means the surface rises 5 units vertically for every 100 units horizontally).

- Versatile: Works for any type of surface, whether it’s a road, pathway, ramp, or slope in an engineering project.

This tool is perfect for engineers, architects, landscapers, and anyone who needs to calculate or analyze the slope of surfaces for construction or design purposes.
