1. What is a 2% Slope?

A 2% slope means that for every 100 units of horizontal distance (run), the elevation changes by 2 units (rise). This is commonly used in engineering, construction, and landscaping for proper drainage and accessibility.

2. How Does the Calculator Work?

The calculator uses the basic slope formula:

For a 2% slope specifically:

• \(\text{Rise} = 0.02 \times \text{Run}\)
• \(\text{Run} = \frac{\text{Rise}}{0.02}\)

Explanation: The calculator can determine any missing value when given two of the three variables (rise, run, or slope percentage).

3. Importance of Slope Calculation

Details: Proper slope calculation ensures adequate drainage, ADA compliance for ramps, and structural stability in construction projects.

4. Using the Calculator

Tips: Enter any two known values to calculate the third. For 2% slope calculations, leave one field blank to calculate it based on 2% slope.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percent slope and degrees?
A: Percent slope is rise/run × 100, while degrees are the arctangent of rise/run. 2% slope ≈ 1.15 degrees.

Q2: Is 2% slope enough for drainage?
A: Yes, 2% is the minimum recommended slope for proper drainage of paved surfaces.

Q3: How do I measure slope in the field?
A: Use a level and measuring tape to determine rise over a known run, or use a digital level or inclinometer.

Q4: What's the maximum slope for an ADA ramp?
A: ADA requires slopes no greater than 1:12 (8.33%) for ramps, with 1:20 (5%) preferred.

Q5: Can I use this for roof pitch calculations?
A: Yes, though roof pitch is often expressed as rise:run ratio (e.g., 4:12) rather than percentage.
