Convert Bearing to Azimuth: Unlocking Navigational Precision

In the realm of navigation, understanding the nuances between bearing and azimuth is paramount. Both terms denote angular measurements, yet their distinctions can significantly impact navigational accuracy.

Bearing is the angle measured clockwise from True North to a specific direction, while azimuth is the angle measured clockwise from True North to a specific direction, but corrected for magnetic declination. Magnetic declination is the angular difference between True North and Magnetic North, and varies depending on location.

Converting Bearing to Azimuth: A Step-by-Step Guide

Step 1: Determine Magnetic Declination

Check reputable sources such as the National Oceanic and Atmospheric Administration (NOAA) to obtain the magnetic declination for your location.

Step 2: Correct Bearing for Declination

Add the magnetic declination (if it's positive) or subtract it (if it's negative) from the bearing to obtain the azimuth.

Azimuth = Bearing ± Magnetic Declination

|| Bearing || Azimuth || Magnetic Declination ||
|:---|:---|:---|:---|
| 15° || 27° || +12° ||
| 280° || 294° || +14° ||
