1. What is Slope Percentage?

Slope percentage is a way to express the steepness of an incline as a ratio of vertical rise to horizontal run, multiplied by 100 to convert it to a percentage. It's commonly used in construction, engineering, and landscaping.

2. How Does the Calculator Work?

The calculator uses the slope percentage formula:

Where:

• \( Rise \) — Vertical height difference (in meters)
• \( Run \) — Horizontal distance (in meters)

Explanation: The formula calculates how much vertical change occurs per unit of horizontal distance, expressed as a percentage.

3. Importance of Slope Calculation

Details: Slope percentage is crucial for designing accessible ramps, proper drainage, road construction, and determining terrain difficulty for various applications.

4. Using the Calculator

Tips: Enter both rise and run values in meters. Both values must be positive numbers. The calculator will compute the slope percentage.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between slope percentage and slope angle?
A: Slope percentage is the ratio expressed as a percentage, while slope angle is the angle in degrees between the incline and horizontal plane.

Q2: What is considered a steep slope?
A: Generally, slopes above 15% are considered steep, with wheelchair ramps typically limited to 8.33% (1:12 ratio).

Q3: How do I measure rise and run in the field?
A: Use a level and measuring tape for small areas, or surveying equipment for larger distances.

Q4: Can I use different units for rise and run?
A: The units must be the same for both rise and run (both in meters, feet, etc.) for the calculation to be valid.

Q5: What does a 100% slope mean?
A: A 100% slope means the rise equals the run (45 degree angle), not vertical as sometimes assumed.
