1. What is Slope Per Foot?

Slope per foot is a measurement that represents the vertical change (rise) per horizontal foot (run). It's commonly used in construction, landscaping, and engineering to determine the gradient or incline of surfaces.

2. How Does the Calculator Work?

The calculator uses the simple slope formula:

Where:

• Rise — Vertical change (in inches)
• Run — Horizontal distance (in feet)

Explanation: The formula calculates how many inches of vertical change occur for every horizontal foot of distance.

3. Importance of Slope Calculation

Details: Accurate slope calculation is crucial for proper drainage, structural stability, accessibility compliance, and ensuring water flows away from buildings correctly.

4. Using the Calculator

Tips: Enter the vertical change in inches and the horizontal distance in feet. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical slope for drainage?
A: For proper drainage, a minimum slope of 1/4 inch per foot is typically recommended, though requirements may vary based on local codes and specific applications.

Q2: How do I convert slope per foot to percentage?
A: Multiply the slope per foot (in decimal form) by 100 to get the percentage slope. For example, 0.25 inches/foot = 25% slope.

Q3: What's the difference between slope per foot and angle?
A: Slope per foot is a linear measurement (inches per foot), while angle is measured in degrees. They can be converted using trigonometric functions.

Q4: When is slope per foot used in construction?
A: It's used for grading, pipe installation, ramp construction, roof pitches, and ensuring proper water flow in drainage systems.

Q5: Can I use different units for rise and run?
A: While inches and feet are standard, you can use any consistent units as long as you maintain the same unit system for both measurements.
