2 chain (US survey) equals approximately 18.992843741 ken.
0.5 chain (US survey) is about 4.748210935 ken.

Common Use Cases

Interpreting and converting distances recorded in historical U.S. land deeds and cadastral surveys.
Adapting legacy survey measurements into Japanese architectural units for design and construction.
Analyzing rural property boundaries and right-of-way descriptions using both unit systems.

Tips & Best Practices

Always verify the historical context of your measurement for accuracy.
Use this conversion when working with historical American land records or Japanese architecture plans.
Consider possible regional variations in ken length when applying results.
Confirm that measurements are based on US survey feet to align with this tool’s assumptions.

Limitations

The US survey chain uses the US survey foot, which differs slightly from the international foot, possibly causing minor inconsistencies internationally.
The ken varies by region and historical period, so exact lengths may differ from our standardized value.
Fixed conversion rates do not account for on-site or local measurement differences.
