Azimuth to Bearing Calculator: Convert Azimuths to Bearings Accurately

Navigating and orienting oneself in the world often involves working with angles and directions. Azimuth and bearing are two important angular measurements used in navigation, surveying, and other fields. An azimuth is the angle measured clockwise from true north, while a bearing is the angle measured clockwise from a reference direction, typically magnetic north.

Importance of Azimuth to Bearing Conversion

Converting azimuths to bearings is crucial in many practical applications. Some examples include:

• Navigation: Sailors and pilots use bearings to determine their direction of travel and calculate their position.
• Surveying: Surveyors use azimuths and bearings to establish boundaries, map terrain, and perform other spatial measurements.
• Construction: Architects and engineers use bearings to align structures and establish building orientations.

Azimuth to Bearing Conversion Formula

The formula for converting azimuths to bearings is:

Bearing = Azimuth - Magnetic Declination

Magnetic declination is the angle between true north and magnetic north. It varies depending on location and time.

Example: Convert an Azimuth to a Bearing

Given an azimuth of 270 degrees, and a magnetic declination of 10 degrees west, the corresponding bearing would be:

Bearing = 270 - 10
= 260 degrees
