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 elevation changes over a given horizontal distance, expressed as a percentage.

3. Importance of Slope Calculation

Details: Slope percentage is crucial for designing accessible ramps, determining proper drainage, planning roads and railways, and ensuring structural stability in construction projects.

4. Using the Calculator

Tips: Enter both rise and run 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, while slopes above 30% are very steep and may require special engineering.

Q3: What's the maximum slope for wheelchair access?
A: ADA guidelines recommend a maximum slope of 8.33% (1:12 ratio) for wheelchair ramps.

Q4: Can I use different units for rise and run?
A: The units must be consistent (both in meters, both in feet, etc.). The calculator currently uses meters.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your rise and run measurements.
