1. What is Angle Of Slope?

The angle of slope represents the inclination or gradient of a surface, measured in degrees from the horizontal plane. It is commonly used in engineering, construction, and geography to describe the steepness of terrain or structures.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

Where:

• \( \text{slope} \) — Slope percentage (%)
• \( \arctan \) — Inverse tangent function

Explanation: The formula converts slope percentage (rise over run × 100) to an angle in degrees using the inverse tangent function.

3. Importance of Angle Calculation

Details: Accurate angle calculation is crucial for proper drainage design, road construction, roof pitching, and ensuring structural stability in various engineering applications.

4. Using the Calculator

Tips: Enter the slope percentage value. The value must be a non-negative number representing the slope percentage.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between slope percentage and angle?
A: Slope percentage represents the vertical rise per 100 units of horizontal distance, while angle represents the inclination in degrees from horizontal.

Q2: What is a typical slope angle for roads?
A: Most roads have slopes between 3-6% (approximately 1.7-3.4 degrees) for proper drainage and vehicle safety.

Q3: How steep is a 45-degree slope in percentage?
A: A 45-degree slope equals a 100% slope (rise equals run).

Q4: What is the maximum recommended slope for wheelchair access?
A: ADA guidelines recommend a maximum slope of 8.33% (approximately 4.76 degrees) for wheelchair ramps.

Q5: Can this calculator handle negative slopes?
A: This calculator is designed for positive slopes only, as negative slopes would represent downward angles which are typically expressed as positive values with direction specified.
