Ramp Slope Formula:
From: | To: |
Ramp slope calculation determines the steepness of a ramp by comparing the vertical rise to the horizontal run. It provides a standardized measure for accessibility and safety compliance.
The calculator uses the slope formula:
Where:
Explanation: The slope represents the ratio of vertical change to horizontal change, providing a dimensionless measure of incline steepness.
Details: Accurate slope calculation is crucial for designing accessible ramps, ensuring safety standards, and meeting building code requirements for wheelchair access and mobility.
Tips: Enter both rise and run values as unitless numbers. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the ideal slope for accessibility ramps?
A: The ADA recommends a maximum slope of 1:12 (8.33%) for wheelchair ramps, though specific requirements may vary by jurisdiction.
Q2: How do I convert slope to percentage?
A: Multiply the slope value by 100 to get the percentage grade (e.g., slope 0.0833 = 8.33% grade).
Q3: What are common slope measurements used in construction?
A: Common measurements include ratio (1:12), decimal (0.0833), percentage (8.33%), and degrees (4.76°).
Q4: Are there limitations to slope calculations?
A: Slope calculations assume a straight, uniform incline and may not account for curved surfaces or variable gradients.
Q5: Why are both values unitless in this calculation?
A: Since slope is a ratio, the units cancel out, making the result dimensionless regardless of the measurement system used.
