1. What is Slope?

Slope is a measure of the steepness or incline of a surface, calculated as the ratio of vertical change (rise) to horizontal change (run). It is a dimensionless value that describes the angle of inclination.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( m \) — Slope (unitless)
• \( \text{rise\_in\_inches} \) — Vertical change in inches
• \( \text{run\_in\_inches} \) — Horizontal change in inches

Explanation: The formula calculates the ratio of vertical change to horizontal change, resulting in a unitless slope value.

3. Importance of Slope Calculation

Details: Slope calculation is essential in various fields including construction, engineering, landscaping, and road design to ensure proper drainage, stability, and safety.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Can slope be expressed as a percentage?
A: Yes, slope can be converted to percentage by multiplying the ratio by 100%.

Q2: What does a slope of 1 mean?
A: A slope of 1 means a 45-degree angle where the rise equals the run.

Q3: How is slope different from grade?
A: Slope is a ratio (rise:run) while grade is typically expressed as a percentage of slope.

Q4: Can I use different units for rise and run?
A: No, both measurements must use the same unit system for accurate slope calculation.

Q5: What's the maximum possible slope value?
A: There's no theoretical maximum, but practical slopes rarely exceed 1:1 (45 degrees) in most applications.
