When working with roads, ramps, roofs, or landscaping, slope measurement is crucial for safety and functionality. Slopes can be represented in degrees or as a percentage (% gradient). Converting between these units helps ensure proper design and compliance with regulations.
A Degree to Percent Slope Calculator simplifies this conversion, providing quick and accurate results.
What Is Slope?
Slope represents the steepness or incline of a surface. It can be expressed in:
- Degrees (°) – The angle of inclination from a horizontal plane.
- Percentage (%) – The vertical rise per 100 units of horizontal run.
The higher the percentage, the steeper the slope. For example, a 10% slope means a 10-unit rise for every 100 units of run.
Formula to Convert Degrees to Percent Slope
To convert a slope from degrees to percentage, use the formula:
Example Calculation
Let’s convert a 30° slope into percentage.
Step 1: Identify Given Values
- Slope Angle (θ) = 30°
Step 2: Apply the Formula
Conclusion
A Degree to Percent Slope Calculator is an essential tool for engineers, architects, and landscapers. It simplifies slope conversion, ensuring accuracy in construction, road planning, and accessibility projects.
