What unit is used for Bearing Error in this workflow?

• A. Degrees
• B. Radians
• C. Minutes
• D. Seconds

Answer: (A)

Bearings are directional angles, so the same unit is used for any deviation from the intended direction. Degrees are the standard way to express a bearing because they map directly to compass directions (0 to 360) and are intuitive for reading on maps and in navigation. Bearing error is simply the angular difference between the observed bearing and the intended one, so expressing that error in degrees keeps the measurement consistent with how the bearing is defined. Subdivisions like minutes or seconds can be used when you need finer precision, but the primary unit remains degrees. Radians are common in pure calculations, but they’re less convenient for reporting bearings in most workflows.
