Frequently Asked Questions

How do I convert OSGB36 to WGS 84 coordinates?

Use the coordinate transformation tool above to convert OSGB36 (EPSG:4277) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 3m accuracy.

How do I transform OSGB36 to WGS 84 using Proj4js?

Use proj4.defs to define both EPSG:4277 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the OSGB36 to WGS 84 transformation?

This transformation (EPSG:5622) has an accuracy of 3m using the Geocentric translations (geog2D domain) method. Area of use: UK - Wytch Farm.
