Slope Ratio Formula:
| From: | To: |
Slope ratio represents the relationship between horizontal distance (run) and vertical distance (rise). It is commonly used in civil engineering, construction, and landscaping to describe the steepness of slopes and gradients.
The calculator uses the slope ratio formula:
Where:
Explanation: The ratio indicates how many units of horizontal distance correspond to one unit of vertical distance. A higher ratio indicates a gentler slope.
Details: Accurate slope ratio calculation is essential for proper drainage design, road construction, ramp accessibility compliance, and ensuring structural stability in various engineering projects.
Tips: Enter horizontal distance (run) and vertical distance (rise) in meters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between slope ratio and slope percentage?
A: Slope ratio is expressed as horizontal:vertical (e.g., 4:1), while slope percentage is (vertical/horizontal)×100%. Ratio focuses on run to rise relationship.
Q2: What does a 3:1 slope ratio mean?
A: A 3:1 slope ratio means for every 3 meters of horizontal distance, there is 1 meter of vertical elevation change.
Q3: When is slope ratio used in construction?
A: Slope ratios are commonly used for embankments, drainage ditches, access ramps, and landscape grading to ensure proper slope stability and functionality.
Q4: What are typical slope ratio values?
A: Common ratios range from 2:1 (steep) to 10:1 (gentle), with 3:1 to 4:1 being typical for many construction applications.
Q5: How does slope ratio affect drainage?
A: Proper slope ratios ensure adequate water flow velocity - too steep may cause erosion, too gentle may cause standing water and poor drainage.
