# Built in conversion methods

Tip

Unless you are trying to register a custom coordinate operation, you do not need to worry about these, they are very much in the realm of implementation detail. For normal use, refer to Coordinate Conversions.

Note

If you are interested in the full details (including formulas) for any particular method, please see the EPSG guidance notes
