1. What is Ramp Gradient?

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

2. How Does the Calculator Work?

The calculator uses the ramp gradient formula:

Where:

• \( Rise \) — Vertical height difference (meters)
• \( Run \) — Horizontal distance (meters)
• \( 100 \) — Conversion factor to percentage

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

3. Importance of Gradient Calculation

Details: Accurate gradient calculation is crucial for accessibility compliance, construction safety, wheelchair ramp design, and ensuring proper drainage in various engineering applications.

4. Using the Calculator

Tips: Enter rise and run values in meters. Both values must be positive numbers greater than zero. The calculator will compute the gradient percentage automatically.

5. Frequently Asked Questions (FAQ)

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

Q2: How does gradient affect ramp usability?
A: Steeper gradients require more effort to ascend and can be dangerous for wheelchair users. Gentle gradients are more accessible and safer.

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

Q4: Can I use this for road gradients?
A: Yes, the same formula applies to road gradients, though road gradients are often expressed as percentages or ratios.

Q5: What is the difference between gradient and slope?
A: Gradient is typically expressed as a percentage, while slope is often expressed as a ratio (e.g., 1:12). They represent the same concept differently.
