Slope Formula:
| From: | To: |
Slope calculation determines the steepness or gradient of a surface, expressed as a percentage. It's essential in construction, landscaping, and civil engineering projects to ensure proper drainage and structural integrity.
The calculator uses the slope percentage formula:
Where:
Explanation: The formula calculates the ratio of vertical rise to horizontal run, multiplied by 100 to express as a percentage.
Details: In UK construction, proper slope calculation is crucial for roof design, drainage systems, accessibility ramps, and landscaping. It ensures compliance with building regulations and prevents water accumulation issues.
Tips: Enter rise and run values in meters. Both values must be positive numbers. The calculator will provide the slope percentage for your construction or landscaping project.
Q1: What is the maximum slope for accessibility ramps in the UK?
A: According to UK building regulations, the maximum slope for accessible ramps is 1:12 (8.33%) for public buildings.
Q2: What slope is recommended for roof drainage?
A: Minimum roof slopes typically range from 1:40 (2.5%) to 1:80 (1.25%) depending on the roofing material and design.
Q3: How do I measure rise and run accurately?
A: Use a spirit level and measuring tape. For longer distances, consider using surveying equipment or laser levels for precise measurements.
Q5: Are there UK building regulations for driveway slopes?
A: Yes, driveways typically should not exceed 5% slope for safety and accessibility, with specific requirements for cross-falls and transitions.
