1. What is the Ramp Slope Degree Calculation?

The ramp slope degree calculation determines the angle of inclination of a ramp based on its vertical rise and horizontal run. This is essential for ensuring ramps meet accessibility standards and safety requirements.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

\[ \theta = \arctan\left(\frac{\text{rise}}{\text{run}}\right) \]

Where:

Explanation: The formula calculates the angle whose tangent is the ratio of rise to run, converting the result from radians to degrees.

3. Importance of Ramp Slope Calculation

Details: Accurate slope calculation is crucial for wheelchair accessibility, building code compliance, construction safety, and ensuring proper drainage and functionality of ramped surfaces.

4. Using the Calculator

Tips: Enter both rise and run values in the same units (meters, feet, etc.). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum recommended slope for wheelchair ramps?
A: ADA guidelines recommend a maximum slope of 1:12 (approximately 4.76 degrees) for wheelchair ramps.

Q2: How do I convert slope percentage to degrees?
A: Slope percentage = (rise/run) × 100. To convert to degrees: θ = arctan(percentage/100).

Q3: What units should I use for rise and run?
A: Use consistent units (both in meters, both in feet, etc.). The calculator works with any unit system as long as both measurements use the same units.

Q4: Can this calculator handle very steep slopes?
A: Yes, the calculator can handle any positive slope values, though extremely steep slopes may not be practical for most applications.

Q5: What's the difference between slope angle and gradient?
A: Slope angle is measured in degrees, while gradient is typically expressed as a ratio (e.g., 1:12) or percentage.
