About This Calculator

This calculator is designed for South African surveying operations using the Lo31 WGS84 coordinate system (Southern Hemisphere). It uses Whole Circle Bearing (WCB) with East = 0°, measured counter-clockwise:

The calculator includes multiple bearing calculation methods for comparison. The WCB East Zero method matches standard SA surveyor software.
