1. What is Ramp Slope?

Ramp slope is the measure of steepness or incline of a ramp, expressed as a percentage. It represents the ratio of vertical rise to horizontal run, multiplied by 100 to convert it to a percentage.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height difference (meters)
• \( Run \) — Horizontal distance (meters)
• \( Slope \% \) — Slope percentage result

Explanation: The formula calculates the incline by dividing the vertical rise by the horizontal run and multiplying by 100 to express it as a percentage.

3. Importance of Slope Calculation

Details: Accurate slope calculation is crucial for designing accessible ramps, ensuring building code compliance, and creating safe inclines for wheelchair users, pedestrians, and vehicles.

4. Using the Calculator

Tips: Enter rise in meters (vertical height), run in meters (horizontal distance). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope for wheelchair ramps?
A: For wheelchair accessibility, maximum slope is typically 1:12 (8.33%) for commercial buildings and 1:8 (12.5%) for residential use.

Q2: How do I convert slope percentage to degrees?
A: Use the formula: degrees = arctan(slope%/100). For example, 10% slope = arctan(0.10) ≈ 5.71 degrees.

Q3: What is considered a gentle slope?
A: Slopes less than 5% are generally considered gentle, while slopes above 10% are considered steep for pedestrian use.

Q4: Why is slope important in construction?
A: Proper slope ensures drainage, accessibility, safety, and compliance with building codes and ADA requirements.

Q5: Can this calculator be used for road gradients?
A: Yes, the same formula applies to road gradients, where rise and run represent elevation change over horizontal distance.
