A long reed is a traditional, now obsolete, unit of length historically used mainly for land measurement and surveying. Its exact length varied depending on locality and period.

What is a US survey link?

The US survey link is a historical unit of length equal to 0.66 US survey feet, used as a subdivision in land surveying and cadastral records in the United States.

Why convert from long reeds to links (US survey)?

Converting from long reeds to links helps interpret and reconcile historical land measurements with modern surveying units, supporting property boundary restoration and engineering projects.

Restoring property boundaries using legacy local surveying data
Interpreting cadastral surveys conducted in obsolete units for civil engineering projects
Supporting historical or linguistic research related to regional measurement standards

Tips & Best Practices

Verify the historical context of the long reed measurement due to its varying length by location and era
Use the conversion for legacy and historical data rather than modern measurements
Cross-reference results when integrating into modern surveying or engineering projects to ensure accuracy
Consider the limitations of rounding and differences between old and current units

Limitations

The long reed's length varied historically, so conversion accuracy depends on contextual knowledge
Rounding and unit standard differences may affect precision
Applicable primarily to historical and legacy measurement data, not modern measurements
