What is a ken unit used for?

Ken is a traditional Japanese length unit used mainly in architecture to specify the spacing between structural pillars and for room layout measurements.

Where is the US survey chain commonly applied?

The US survey chain is traditionally used in U.S. land surveying, cadastral work, and property boundary descriptions.

Is the conversion between ken and chain exact?

No, the conversion is approximate since the units originate from different historical measurement systems with slight variations.

What Is This Tool?

This converter transforms length values from ken, a traditional Japanese measurement linked to building proportions, into the US survey chain, a historic unit used in American land surveys.

How to Use This Tool?

Enter the length value in ken.
Select the target unit as chain (US survey) [ch].
Execute the conversion to see the equivalent length in chains.

Key Features

Converts ken units used in traditional Japanese architecture to US survey chains.
Supports applications in land surveying, cultural heritage, and geographic information systems.
Offers straightforward, browser-based length conversion with a simple formula.

Examples

5 ken converts to approximately 0.5265 chain (US survey) [ch].
10 ken converts to roughly 1.0530 chain (US survey) [ch].

Common Use Cases

Translating traditional Japanese architectural measurements to U.S. surveying units.
Interpreting historical land deeds and cadastral surveys in U.S. contexts.
Integrating traditional layout dimensions with modern GIS and mapping data.

Tips & Best Practices

Ensure accurate input values to maintain meaningful conversion results.
Use this conversion when working with mixed cultural or historical measurement systems.
Be mindful of subtle differences in unit definitions when applying results in precise contexts.

Limitations

Conversion involves minor approximations due to differing historical measurement standards.
The ken unit may vary regionally and historically despite a common standard.
The US survey chain relies on the US survey foot, which differs slightly from the international foot.
