Slope Formula:
| From: | To: |
The slope to degrees conversion calculates the angle of inclination from a slope ratio using the inverse tangent (arctangent) function. This is essential in various fields including engineering, construction, and geography.
The calculator uses the mathematical formula:
Where:
Explanation: The arctangent function converts the slope ratio (rise over run) into an angle measured in degrees, providing a more intuitive understanding of the incline.
Details: Calculating slope angles is crucial for proper drainage design, road construction, roof pitching, wheelchair ramp installation, and various engineering applications where precise incline measurements are required.
Tips: Enter the slope ratio (e.g., 0.5 for a 1:2 slope). The calculator will automatically compute the corresponding angle in degrees. Positive values represent upward slopes, while negative values represent downward slopes.
Q1: What's the difference between slope ratio and angle?
A: Slope ratio expresses incline as a ratio (e.g., 1:4), while angle expresses it in degrees, which is often more intuitive for visualization.
Q2: What is the maximum slope angle?
A: The maximum theoretical slope angle is 90° (vertical), but practical applications rarely exceed 45° due to stability and safety concerns.
Q3: How does this relate to grade percentage?
A: Grade percentage is slope × 100%. A 45° angle equals a 100% grade. Our calculator converts slope ratio directly to degrees.
Q4: Can I calculate negative slopes?
A: Yes, negative slope values will calculate negative angles, representing downward slopes or declines.
Q5: What fields use slope angle calculations?
A: Civil engineering, architecture, landscaping, road construction, geology, and many other technical fields regularly use slope angle calculations.
