1. What is Ramp Slope Calculation?

Ramp slope calculation determines the steepness or gradient of a ramp by comparing the vertical rise to the horizontal run. It is expressed as a percentage and is crucial in construction, accessibility design, and engineering applications.

2. How Does the Calculator Work?

The calculator uses the slope percentage formula:

Where:

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

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

3. Importance of Slope Percentage

Details: Slope percentage is essential for ensuring ramp accessibility compliance, determining vehicle ramp requirements, designing drainage systems, and meeting building code specifications for safe and functional slopes.

4. Using the Calculator

Tips: Enter both rise and run values in meters. Ensure measurements are accurate and both values are greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope for wheelchair ramps?
A: According to ADA standards, the maximum slope for wheelchair ramps is 8.33% (1:12 ratio) for commercial applications.

Q2: How does slope percentage relate to degrees?
A: Slope percentage = tan(angle) × 100. For example, a 45° angle equals 100% slope.

Q3: What slope is suitable for vehicle ramps?
A: Vehicle ramps typically range from 10% to 20% slope, depending on the vehicle type and usage requirements.

Q4: Can I use different units for rise and run?
A: Yes, as long as both measurements use the same units (feet, meters, etc.), the calculation will be accurate.

Q5: What does a negative slope percentage indicate?
A: Negative slope indicates a downward slope or decline, while positive indicates an upward slope or incline.
