What Is This Tool?
This tool converts measurements from ken, a traditional Japanese unit of length, into link (US survey) units, which are historical small subdivisions used in land surveying in the United States. It helps translate between measurement systems commonly found in architectural restoration, historical mapping, and cadastral record analysis.
How to Use This Tool?
-
Enter the length value in ken units into the input field
-
Select 'ken' as the source unit and 'link (US survey) [li]' as the target unit
-
Click the convert button to see the equivalent measurement in links
-
Use the output for historical or technical analysis involving both units
Key Features
-
Converts ken units to link (US survey) with a fixed conversion rate
-
Supports specialized use cases in architecture and land surveying
-
Browser-based and easy to use without additional software
-
Provides examples to illustrate the conversion process
Examples
-
2 Ken converts to approximately 21.06 link (US survey) [li]
-
5 Ken converts to approximately 52.65 link (US survey) [li]
Common Use Cases
-
Specifying bay widths in traditional Japanese buildings using ken and converting to US survey measurements
-
Interpreting historic US land survey plats and deeds that use link (US survey) units
-
Reconciling building dimensions in carpentry and historic plans with land surveying data
-
Supporting civil engineering projects involving legacy cadastral records
Tips & Best Practices
-
Use this tool primarily for historical or specialized measurement conversions
-
Double-check the context of the units due to potential minor variations in ken standards
-
Remember that link (US survey) is a legacy unit and might require conversion to modern units for practical applications
-
Verify conversion results when working with survey or architectural precision requirements
Limitations
-
Ken is standardized approximately and may vary slightly in historical use
-
Link (US survey) is largely replaced by metric or customary US units today
-
Conversion precision may be affected by rounding and specific survey standards
-
The tool is intended for specialized historical or technical contexts, not everyday measurements
Frequently Asked Questions
-
What is a ken unit used for?
-
Ken is a traditional Japanese length unit used mainly in architecture to measure bay widths between pillars and in room sizing.
-
Why convert ken to link (US survey)?
-
This conversion helps relate traditional Japanese measurements to historic US land surveying units for purposes like architectural restoration and cadastral analysis.
-
Is the link (US survey) still commonly used?
-
No, the link (US survey) is a legacy unit mostly replaced by metric or standard US customary measurements.
Key Terminology
-
Ken
-
A traditional Japanese unit of length used primarily in architecture, equal to six shaku or about 1.818 meters.
-
Link (US survey)
-
A historical US land surveying unit equal to 1/100 of a Gunter's chain, approximately 0.201168 meters.
-
Cadastral records
-
Documents and maps detailing land ownership and boundaries, often using legacy units in historic surveys.
