What Is This Tool?
This converter transforms lengths measured in US survey miles into ken, a traditional Japanese unit of length used in construction and architectural layouts. It is designed to support cross-cultural projects involving legacy US land survey units and classical Japanese building measurements.
How to Use This Tool?
-
Enter the value in mile (US survey) you wish to convert.
-
Select mile (US survey) as the input unit and ken as the output unit.
-
Click convert to obtain the equivalent length in ken.
-
Use the results to interpret or translate between US surveying distances and Japanese architectural dimensions.
Key Features
-
Convert US survey miles to ken instantly using an exact conversion rate.
-
Supports heritage and surveying applications bridging American and Japanese measurement systems.
-
Browser-based and easy to operate without prior technical knowledge.
-
Provides clear examples of common conversions for quick reference.
Examples
-
1 mile (US survey) equals 759.7137496433 ken.
-
2 miles (US survey) correspond to 1519.4274992866 ken.
Common Use Cases
-
Converting legacy cadastral land measurements for traditional Japanese architecture projects.
-
Interpreting older American survey data when working with Japanese building layouts.
-
Cross-cultural academic research involving historic building proportions and land divisions.
Tips & Best Practices
-
Always verify which definition of ken applies in your specific historical or regional context.
-
Use this tool to support interpretation rather than as an absolute measurement due to slight traditional variability.
-
Consider the difference between the US survey mile and the international mile in your projects.
-
Complement with official surveying data for precise legal land descriptions.
Limitations
-
The ken unit length may vary historically or regionally, so conversions are approximate.
-
The US survey mile differs slightly from the international mile, relevant mainly in US-specific surveying.
-
Practical conversions may need calibration when integrating data from distinct measurement systems.
Frequently Asked Questions
-
What is a US survey mile?
-
It is a unit of length equal to exactly 5,280 US survey feet, used primarily in US land surveying and mapping to maintain consistency with historical measurements.
-
How is ken used in Japanese architecture?
-
Ken is a traditional modular unit approximately 1.818 meters long, used to specify bay widths between pillars and room layout proportions in temples, shrines, and other structures.
-
Why convert US survey miles to ken?
-
To integrate and compare American surveying distances with Japanese traditional modular measurements in heritage architecture and research.
