1. What is Slope Degrees Calculation?

Slope degrees calculation converts the slope ratio (rise over run) into angular degrees, providing a more intuitive understanding of the incline's steepness in geometric terms.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

\[ Degrees = \arctan(Slope) \times \frac{180}{\pi} \]

Where:

Explanation: The arctangent function converts the slope ratio to an angle in radians, which is then converted to degrees using the 180/π multiplier.

3. Importance of Slope Angle Calculation

Details: Calculating slope degrees is essential in construction, engineering, road design, roofing, and various technical fields where precise angle measurements are required for safety and functionality.

4. Using the Calculator

Tips: Enter the slope as a ratio (rise divided by run). For example, a slope of 1:2 would be entered as 0.5. The value must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between slope ratio and degrees?
A: Slope ratio expresses steepness as a proportion (rise/run), while degrees express it as an angle from horizontal, making it easier to visualize.

Q2: What is a typical roof slope in degrees?
A: Residential roofs typically range from 15° to 45°, with steeper slopes providing better water drainage.

Q3: How do I convert degrees back to slope ratio?
A: Use the formula: Slope = tan(Degrees × π/180)

Q4: What's the maximum possible slope in degrees?
A: The theoretical maximum is 90° (vertical), but practical slopes rarely exceed 45° for most applications.

Q5: Why use degrees instead of percentage?
A: Degrees provide a true angular measurement, while percentage slope is rise over run × 100, which can be misleading for very steep slopes.
