What is the relationship between a link and a chain in US survey units?

One link (US survey) equals 0.01 of a chain (US survey), meaning 100 links make one chain.

Why are these units important in land surveying?

Links and chains have been historically used for land measurement and cadastral records in the US, particularly in legacy survey plats and deeds.

Can I use this conversion tool for modern international measurements?

No, this tool is specifically for US survey units and may not directly apply to modern international foot-based measurements without adjustments.

What Is This Tool?

This tool allows users to convert length measurements from link (US survey) to chain (US survey), units traditionally used in American land surveying and cadastral records. It simplifies calculating and interpreting legacy survey distances.

How to Use This Tool?

Enter the measurement value in link (US survey) units.
Select 'link (US survey) [li]' as the input unit and 'chain (US survey) [ch]' as the output unit.
Click the convert button to get the equivalent value in chains (US survey).
Use the conversion results for interpreting or updating historical survey records.

Key Features

Converts length units specifically from link (US survey) to chain (US survey).
Incorporates historical measurement standards based on the US survey foot.
Browser-based and easy to use for professionals dealing with legacy survey data.
Supports accurate aggregation of smaller units (links) into larger units (chains).

Examples

50 link (US survey) converts to 0.5 chain (US survey) by multiplying 50 × 0.01.
100 link (US survey) equals 1 chain (US survey) as per the formula 100 × 0.01.

Common Use Cases

Interpreting distances from historical US land survey plats and deeds.
Converting legacy survey measurements to modern units for mapping and GIS applications.
Facilitating civil engineering or land transfer projects that integrate older survey data.
Describing rural property boundary surveys and right-of-way details.

Tips & Best Practices

Use this tool when working with historical US survey data involving links and chains.
Consider the difference between US survey foot and international foot for precision tasks.
Aggregate smaller link units into chains to simplify land measurement interpretation.
Verify converted values against original survey documentation for accuracy in boundary determinations.

Limitations

Units are based on the US survey foot, which slightly differs from the international foot, affecting exact precision.
These units are mainly applicable to legacy survey data and may not align with modern surveying standards without adjustments.
