bng2latlong

API

Convert British National Grid (OSGB36) coordinates to WGS84 latitude and longitude

Overview

The bng2latlong API offers a RESTful endpoint to convert British OSGB36 easting and northing (British National Grid) coordinates to WGS84 latitude and longitude. Users send GET requests with numeric easting and northing parameters to receive converted coordinates in JSON format. Ideal for developers integrating UK spatial data into global mapping tools, converting legacy British location datasets to GPS-compatible WGS84 standards, or building location-aware apps focused on the UK. No authentication is required, enabling quick and easy integration into any project.

Example Integration (JavaScript)
