1. What is Slope Calculation?

Slope calculation determines the steepness or gradient of a surface, expressed as a percentage. It's commonly used in construction, landscaping, and engineering to measure incline.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

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

Explanation: The formula calculates the ratio of vertical change to horizontal change, multiplied by 100 to convert to percentage.

3. Importance of Slope Calculation

Details: Accurate slope calculation is crucial for proper drainage planning, road construction, ramp design, and ensuring structural stability in various construction projects.

4. Using the Calculator

Tips: Enter rise and run values in feet. Both values must be positive numbers, with run greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical slope for drainage?
A: For proper drainage, a minimum slope of 2% (2 feet per 100 feet) is generally recommended.

Q2: How is slope different from angle?
A: Slope is expressed as a percentage or ratio, while angle is measured in degrees. They can be converted using trigonometric functions.

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

Q4: Can I use different units for rise and run?
A: The units must be consistent. If using different units, convert them to the same unit before calculation.

Q5: What does a 100% slope mean?
A: A 100% slope means the rise equals the run, which corresponds to a 45-degree angle.
