1. What is Reverse Bearing?

Reverse bearing is the direction exactly opposite to a given bearing. It is calculated by adding 180 degrees to the original bearing and then taking modulo 360 to ensure the result stays within the 0-360 degree range.

2. How Does the Calculator Work?

The calculator uses the reverse bearing formula:

\[ RB = (bearing + 180) \mod 360 \]

Where:

Explanation: The formula calculates the exact opposite direction by adding 180 degrees and using modulo 360 to handle cases where the result exceeds 360 degrees.

3. Importance of Reverse Bearing Calculation

Details: Reverse bearing calculation is essential in navigation, surveying, and concrete construction for determining return paths, verifying measurements, and ensuring accurate directional alignment.

4. Using the Calculator

Tips: Enter the bearing in degrees (0-360). The value must be a valid bearing measurement between 0 and 360 degrees.

5. Frequently Asked Questions (FAQ)

Q1: Why is reverse bearing important in concrete construction?
A: In concrete construction, reverse bearing helps ensure proper alignment of forms, verify measurement accuracy, and calculate return paths for equipment and material placement.

Q2: What is the range of valid bearing values?
A: Bearings are typically measured in degrees from 0 to 360, where 0/360 is north, 90 is east, 180 is south, and 270 is west.

Q3: How does modulo operation work in this calculation?
A: The modulo operation ensures that when bearing + 180 exceeds 360, it wraps around to the appropriate value within the 0-360 range (e.g., 270 + 180 = 450, mod 360 = 90).

Q4: Can this calculator be used for magnetic bearings?
A: Yes, the calculator works for both true bearings and magnetic bearings, as long as the input is in degrees from 0 to 360.

Q5: Are there any special considerations for concrete applications?
A: For concrete work, ensure all bearings are measured consistently and account for any site-specific magnetic declination if using magnetic bearings.
