Azimuth and Bearing Converter

Convert azimuths to bearings and back with this precise, survey-ready converter for civil surveying and navigation.

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

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.

Formulas

Azimuth to Bearing: Bearing = (Azimuth + 180) % 360

Bearing to Azimuth: Azimuth = (Bearing - 180 + 360) % 360

The input angle is normalized to the 0°–360° range before applying either adjustment so the output stays within the same bounds.
