1. What is Elevation Degree?

Elevation degree measures the angle between the horizontal plane and the line of sight to an object. It's commonly used in surveying, engineering, and navigation to determine the steepness or inclination of a surface.

2. How Does the Calculator Work?

The calculator uses the elevation degree formula:

Where:

• \( \text{Slope} \) — The ratio of vertical change to horizontal change (rise over run)
• \( \arctan \) — The inverse tangent function
• \( \pi \) — Mathematical constant pi (~3.14159)

Explanation: The formula converts a slope ratio (like 1:10) into an angle in degrees that represents the elevation.

3. Importance of Elevation Calculation

Details: Calculating elevation degrees is essential for construction projects, road design, wheelchair ramp compliance, roof pitch determination, and various engineering applications.

4. Using the Calculator

Tips: Enter the slope as a decimal value (e.g., for a 1:10 slope, enter 0.1). The calculator will return the equivalent angle in degrees.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between slope and elevation degree?
A: Slope is a ratio (rise:run) while elevation degree is the angle formed by that slope.

Q2: How do I convert percentage grade to slope?
A: Percentage grade is slope × 100 (e.g., 10% grade = 0.1 slope).

Q3: What's the maximum possible elevation degree?
A: Theoretically 90° (vertical), but practical applications rarely exceed 45°.

Q4: Can I calculate slope from elevation degree?
A: Yes, slope = tan(degrees × π/180).

Q5: Why use degrees instead of radians?
A: Degrees are more intuitive for most practical applications and standard in many fields.
