How to Use This Converter
Enter the angle you need to convert and pick whether you are translating an azimuth into a bearing or the reverse. Click Calculate or wait a heartbeat for the result to appear once you make a change.
Methodology & Data Source
Calculations rely on standard surveying guidelines for azimuth and bearing conversions. The approach normalizes the input angle to 0°–360°, applies the adjustment, and keeps results in that same range so you can read values directly from field notes or navigation charts.
Audit note: This section documents the formulas used by the calculator engine. No additional variables were provided in the audit spec.
Glossary of Terms
- Azimuth: A horizontal angle measured clockwise from a north baseline.
- Bearing: The angle between a reference direction (north or south) and a line.
Step-by-Step Example
If you start with an azimuth of 120°, add 180° and take the remainder modulo 360° to arrive at a bearing of 300°. The tool does the same math automatically and keeps both the input and output normalized.
Frequently Asked Questions
- What is an Azimuth?
- A direction expressed as the angle from a reference north line, measured clockwise.
- How is a Bearing different?
- A bearing is the angle between a reference north or south direction and the line, read clockwise or counter-clockwise depending on convention.
- Why convert between the two?
- Surveyors and navigators convert between azimuths and bearings to interpret or translate directional information accurately.
- Are the conversions accurate?
- Yes, the conversion uses the same arithmetic step-by-step that field and classroom reference tables recommend.
- Can I rely on this for navigation?
- The tool gives you precise numerical conversions that match the conventions used in surveying and map work.
