1. What is Ramp Gradient?

Ramp gradient is a measure of the steepness or incline of a slope, calculated as the ratio of vertical rise to horizontal run. It is commonly used in construction, engineering, and accessibility planning to determine the slope of ramps, roads, and other inclined surfaces.

2. How Does the Calculator Work?

The calculator uses the gradient formula:

Where:

• \( Rise \) — Vertical change (height difference)
• \( Run \) — Horizontal change (length along the slope)

Explanation: The gradient represents how much vertical elevation changes per unit of horizontal distance. A higher gradient indicates a steeper slope.

3. Importance of Gradient Calculation

Details: Accurate gradient calculation is crucial for ensuring accessibility compliance, structural stability, proper drainage, and safety in various construction and engineering projects.

4. Using the Calculator

Tips: Enter 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 units should I use for rise and run?
A: Use consistent units for both measurements (e.g., both in meters or both in feet). The gradient result is unitless.

Q2: How is gradient different from slope percentage?
A: Gradient is a ratio (rise/run), while slope percentage is gradient multiplied by 100%. For example, a gradient of 0.08 equals an 8% slope.

Q3: What is considered a steep gradient?
A: Steepness depends on context. For wheelchair ramps, gradients above 1:12 (0.083) are generally too steep. For roads, gradients above 6-8% are considered steep.

Q4: Can gradient be greater than 1?
A: Yes, gradients greater than 1 indicate slopes steeper than 45 degrees, where the vertical rise exceeds the horizontal run.

Q5: How does gradient affect accessibility?
A: Lower gradients are more accessible. ADA guidelines typically recommend gradients no steeper than 1:12 (0.083) for wheelchair ramps.
