1. What is the Angle Calculation Formula?

The angle calculation formula converts a slope value (rise over run) into an angle measured in degrees. This is particularly useful in geometry, engineering, and various technical fields where slope-to-angle conversion is required.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

Where:

• \( \text{Slope} \) — The ratio of vertical rise to horizontal run (dimensionless)
• \( \arctan \) — Inverse tangent function
• \( \frac{180}{\pi} \) — Conversion factor from radians to degrees

Explanation: The arctangent function calculates the angle in radians, which is then converted to degrees using the conversion factor.

3. Importance of Angle Calculation

Details: Accurate angle calculation from slope is essential in construction, road design, roof pitch determination, and various engineering applications where precise angular measurements are required.

4. Using the Calculator

Tips: Enter the slope value (rise divided by run) as a dimensionless number. Positive values indicate upward slopes, negative values indicate downward slopes.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of possible angle values?
A: The calculated angle ranges from -90° to +90°, covering all possible slope conditions.

Q2: How is slope different from angle?
A: Slope is a ratio (rise/run) while angle is measured in degrees. This calculator converts between the two measurements.

Q3: Can I use this for steep slopes?
A: Yes, the formula works for all slope values, including very steep slopes approaching vertical (90°).

Q4: What about negative slope values?
A: Negative slope values will result in negative angle values, indicating a downward slope or decline.

Q5: Are there any limitations to this calculation?
A: The calculation assumes a straight line and may not account for curvature in more complex geometric situations.
