1. What is the Angle Degree Calculator?

The Angle Degree Calculator calculates the angle in degrees from the rise and run measurements using trigonometric principles. It's commonly used in construction, engineering, and geometry applications.

2. How Does the Calculator Work?

The calculator uses the arctangent formula:

Where:

• \( \theta \) — Angle in degrees
• \( Rise \) — Vertical height difference
• \( Run \) — Horizontal distance
• \( \arctan \) — Inverse tangent function
• \( \frac{180}{\pi} \) — Conversion factor from radians to degrees

Explanation: The ratio of rise to run gives the tangent of the angle, and taking the arctangent of this ratio gives the angle in radians, which is then converted to degrees.

3. Importance of Angle Calculation

Details: Accurate angle calculation is essential for roof pitch determination, road grading, ramp construction, and various engineering applications where slope and inclination matter.

4. Using the Calculator

Tips: Enter rise and run values in meters (or any consistent unit). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for rise and run?
A: You can use any units (meters, feet, inches) as long as both rise and run use the same unit system.

Q2: What is the difference between degrees and percent grade?
A: Degrees measure the actual angle, while percent grade is (rise/run) × 100%. A 45° angle equals 100% grade.

Q3: Can I calculate slope from angle?
A: Yes, slope = tan(angle in degrees × π/180). The calculator essentially does the reverse of this process.

Q4: What is the maximum angle this calculator can handle?
A: Theoretically up to 90°, but practically limited by the rise/run ratio. As run approaches 0, the angle approaches 90°.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your rise and run measurements.
