Slope Calculation Formula:
| From: | To: |
Slope calculation converts an angle in degrees to a rise/run ratio, typically expressed in inches per foot for construction and engineering applications. This is particularly useful for roof pitch, ramp design, and drainage systems.
The calculator uses the slope formula:
Where:
Explanation: The tangent of the angle represents the ratio of vertical rise to horizontal run. Multiplying by 12 converts this ratio to inches per foot, which is the standard measurement in construction.
Details: Accurate slope calculation is essential for proper drainage, structural integrity, and compliance with building codes. It ensures water flows correctly off surfaces and that ramps meet accessibility standards.
Tips: This calculator is preset to calculate the slope for a 5-degree angle. Simply click the Calculate button to see the result in inches per foot.
Q1: Why is slope measured in inches per foot?
A: Inches per foot is a standard measurement in construction and engineering that provides a practical understanding of how much vertical rise occurs over a one-foot horizontal distance.
Q2: What is the slope for a 5-degree angle?
A: A 5-degree slope equals approximately 1.05 inches per foot, meaning for every foot of horizontal distance, the surface rises about 1.05 inches.
Q3: Where is a 5-degree slope commonly used?
A: 5-degree slopes are often used for wheelchair ramps, drainage systems, and low-pitch roofs where minimal slope is needed for water runoff.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise, using the tangent function to convert degrees to a slope ratio. The result is rounded to four decimal places for practical use.
Q5: Can I calculate other angles with this calculator?
A: This calculator is specifically designed for 5-degree slopes. For other angles, you would need to modify the angle value in the code.
