Assumptions and limitations

The U.S. survey foot became obsolete in 2023 and is retained here for legacy records. Unit conversion alone is not a coordinate-system or datum transformation.

How to use this tool

Set up the inputs

Check the unit recorded in the original survey, then choose survey or international feet explicitly.

Worked examples
