1. What is True Bearing?

True Bearing is the horizontal angle measured clockwise between the true meridian and the line. It represents the actual direction from true north.

2. How Does the Calculator Work?

The calculator uses the True Bearing formula:

Where:

• \( TB \) — True Bearing (radians)
• \( MB \) — Magnetic Bearing (radians)
• \( MD \) — Magnetic Declination (radians)

Explanation: When magnetic declination is east, true bearing is calculated by adding the magnetic declination to the magnetic bearing.

3. Importance of True Bearing Calculation

Details: Accurate true bearing calculation is crucial for navigation, surveying, and mapping applications where precise directional measurements are required.

4. Using the Calculator

Tips: Enter magnetic bearing and magnetic declination in radians. Both values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is magnetic declination?
A: Magnetic Declination is the horizontal angle between true north and magnetic north at the time of observation.

Q2: Why add declination when it's east?
A: When magnetic north is east of true north, you add the declination to convert from magnetic to true bearing.

Q3: What units should be used for input?
A: The calculator expects input values in radians for both magnetic bearing and magnetic declination.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, but accuracy depends on the accuracy of the input measurements.

Q5: Can this calculator handle negative values?
A: No, the calculator only accepts non-negative values for both magnetic bearing and magnetic declination.
