What is a Chain in surveying?

A Chain is a traditional unit of length equal to 66 feet, commonly used in historic land measurements and divided into 100 Links.

How many Links are in one Chain?

One Chain equals approximately 99.9998 Links in the US survey system.

Why convert from Chain to Link (US survey)?

Converting helps translate larger traditional land units into smaller subdivisions for detailed cadastral and surveying purposes.

How to Convert from Chain [ch] to Link (US survey) [li]

Common Use Cases

Decoding and converting historical property deeds and survey plans into modern units.
Cadastral surveying and mapping for land parcel boundary analysis.
Reconciling legacy land measurement records for civil engineering and GIS projects.
Working with US land survey plats and boundary descriptions in legacy datasets.

Tips & Best Practices

Always verify the unit definitions when dealing with historic survey data.
Check for precision limitations if performing large-scale calculations to avoid accumulated errors.
Confirm conversions against current standards when integrating with modern metric measurements.
Use the tool for detailed subdividing of larger land measurement units for cadastral clarity.

Limitations

The conversion factor of 99.9998 links per chain is very close but not exactly 100, which can cause small discrepancies.
Large-scale calculations may accumulate minor errors due to historical precision variance.
Modern surveying increasingly uses metric units, so conversions require careful cross-checking.
This tool is designed specifically for converting Chain to Link (US survey) and may not apply to other unit systems.
