1. What is Ramp Slope Gradient?

Ramp slope gradient is a measure of the steepness 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 value.

2. How Does the Calculator Work?

The calculator uses the gradient formula:

Where:

• \( Rise \) — Vertical distance (meters)
• \( Run \) — Horizontal distance (meters)
• \( Gradient \) — Slope percentage (%)

Explanation: The formula calculates the ratio of vertical height gained to horizontal distance covered, then converts it to a percentage for easier interpretation.

3. Importance of Gradient Calculation

Details: Gradient calculation is essential for designing accessible ramps, construction projects, road design, and ensuring compliance with building codes and accessibility standards.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in meters. Both values must be positive numbers greater than zero for accurate calculation.

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 differ from angle?
A: Gradient is expressed as a percentage or ratio, while angle is measured in degrees. Gradient = tan(angle) × 100%.

Q3: What gradient is considered steep for vehicles?
A: For vehicles, gradients above 10% are considered steep, while gradients above 20% are very steep and may require special considerations.

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

Q5: What is the relationship between gradient and slope ratio?
A: Gradient percentage and slope ratio are related: a 1:10 slope equals 10% gradient, 1:12 equals 8.33%, and 1:20 equals 5%.
