A reed is an obsolete or regional length unit historically based on reed plants or measuring rods, varying in exact value across cultures and time periods.

How is ken used in traditional Japanese architecture?

Ken serves as a modular length measuring bays or spacing between structural pillars, and helps determine room and tatami sizes.

Why might conversions between reed and ken be approximate?

Because the reed varied historically by location and the ken may have regional architectural variations, exact conversion can be imprecise.

What Is This Tool?

This converter helps you change length values from the reed, a historical and regional unit, into ken, a traditional Japanese measurement used primarily in architecture and spatial design. It is useful for understanding measurements in historical, cultural, and architectural contexts.

How to Use This Tool?

Enter the length value in reeds that you want to convert.
Select the unit 'reed' as the starting measurement.
Choose 'ken' as the target unit for conversion.
Click the convert button to see the equivalent length in ken.
Use the result to assist with your historical or architectural analysis.

Key Features

Converts length from reed to ken using established conversion rates.
Supports understanding of archaic and traditional units in historical and architectural fields.
Browser-based, easy to use without additional software.
Facilitates interpretation of old documents, building plans, and ethnographic data.

Examples

2 Reeds equal 2 multiplied by 1.2949640288, resulting in approximately 2.5899280576 Ken.
5 Reeds equal 5 multiplied by 1.2949640288, resulting in approximately 6.474820144 Ken.

Common Use Cases

Interpreting measurements from historical land deeds or maps using archaic units.
Researching traditional Japanese architecture and bay spacing between pillars.
Analyzing ethnographic or archaeological records involving obsolete length units.
Assisting legal or land document examination involving old units of length.

Tips & Best Practices

Consider the historical context since the length of a reed varied by location and period.
Use the conversion as an approximate guide when precise historical values are unknown.
Cross-reference architectural records when converting ken values due to possible regional differences.
Apply conversions carefully for accurate interpretation in cultural and building research.

Limitations

The reed unit's value changed historically depending on locality, so conversions may only be approximate.
The ken is standardized but can slightly vary regionally or by older architectural use.
Fixed conversion rates used may not reflect all historical measurement inconsistencies.
