1. What is Wheelchair Ramp Slope Calculation?

The wheelchair ramp slope calculation determines the incline percentage of a ramp using metric measurements. It calculates the slope as a percentage based on the vertical rise and horizontal run of the ramp.

2. How Does the Calculator Work?

The calculator uses the slope percentage formula:

\[ Slope\_Percent = \frac{Rise}{Run} \times 100 \]

Where:

\( Rise \) — Vertical height in centimeters (cm)
\( Run \) — Horizontal length in centimeters (cm)
\( Slope\_Percent \) — Resulting slope percentage (%)

Explanation: The formula calculates the ratio of vertical height to horizontal length and converts it to a percentage by multiplying by 100.

3. Importance of Proper Ramp Slope

Details: Proper ramp slope is crucial for wheelchair accessibility, safety, and compliance with building codes. Steep slopes can be dangerous and difficult to navigate.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in centimeters. 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: The maximum recommended slope is typically 8.33% (1:12 ratio) for commercial buildings, though steeper slopes may be acceptable for residential use with proper safety features.

Q2: How do I convert slope percentage to ratio?
A: Divide 100 by the slope percentage. For example, 8.33% slope equals 1:12 ratio (100 ÷ 8.33 ≈ 12).

Q3: What are the building code requirements for ramp slopes?
A: Most building codes require a maximum slope of 1:12 (8.33%) for accessible routes, with specific requirements for landing platforms and handrails.

Q4: Can this calculator be used for other types of slopes?
A: Yes, the same formula applies to any slope calculation where you need to determine the incline percentage from rise and run measurements.

Q5: What if I have measurements in different units?
A: Convert all measurements to centimeters before using the calculator, or adjust the formula accordingly for consistent units.
