1. What is Slope Ratio?

Slope Ratio represents the steepness or incline of a line, calculated as the ratio of vertical change (rise) to horizontal change (run). It is a fundamental concept in mathematics, engineering, and construction.

2. How Does the Calculator Work?

The calculator uses the slope ratio formula:

Where:

• \( Rise \) — Vertical change (units)
• \( Run \) — Horizontal change (units)

Explanation: The slope ratio indicates how much vertical change occurs for each unit of horizontal change. A higher ratio means a steeper slope.

3. Importance of Slope Ratio Calculation

Details: Slope ratio is crucial for road design, roof construction, wheelchair ramps, drainage systems, and any application where incline affects functionality and safety.

4. Using the Calculator

Tips: Enter rise and run values in the same units (meters, feet, etc.). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between slope ratio and slope percentage?
A: Slope ratio is expressed as a ratio (e.g., 1:4), while slope percentage is the ratio multiplied by 100 (e.g., 25%).

Q2: What is considered a steep slope?
A: Generally, slopes greater than 1:3 (33%) are considered steep, but this varies by application and local regulations.

Q3: How is slope ratio used in construction?
A: It's used for roof pitches, road grades, ramp accessibility standards, and drainage system design.

Q4: Can slope ratio be greater than 1?
A: Yes, when the rise is greater than the run, the slope ratio will be greater than 1, indicating a steep incline.

Q5: What units should I use for rise and run?
A: Use consistent units (both in meters, both in feet, etc.). The ratio itself is unitless.
