What is an aln unit used for historically?

Aln is a Scandinavian historical length unit used for measuring cloth, textiles, and room or building dimensions in older architectural records.

What does the US survey chain measure?

The US survey chain is a traditional length unit used in land surveying, equivalent to 66 US survey feet, used historically in U.S. cadastral and boundary surveys.

Why might this conversion have accuracy limitations?

Because aln varies by region and time period, and the US survey chain uses the US survey foot which differs slightly from the international foot, minor discrepancies can occur.

What Is This Tool?

This converter transforms measurements from aln, an old Scandinavian length unit used for cloth and architecture, into chain (US survey) [ch], a unit historically used in U.S. land surveying and cadastral mapping.

How to Use This Tool?

Enter the value in aln that you want to convert.
Select aln as the input unit and chain (US survey) [ch] as the output unit.
Click convert to get the equivalent length in chains.

Key Features

Converts historical Scandinavian aln units to US survey chain measurements.
Supports accurate integration of legacy measurement data for land survey and GIS projects.
Provides clear conversion examples for quick reference.

Examples

10 aln equals 0.295164534 chain (US survey) [ch].
100 aln converts to 2.95164534 chain (US survey) [ch].

Common Use Cases

Interpreting Scandinavian textile measurements in historical trade records.
Analyzing Swedish, Norwegian, or Danish architectural documents for room dimensions.
Converting legacy Scandinavian lengths into US surveying units for cadastral mapping and GIS data integration.
Studying heritage architecture or historic land surveys involving mixed measurement systems.

Tips & Best Practices

Always verify the historical context of the aln measurement due to length variations by country and period.
Use this conversion mostly for general comparison and integration rather than precision-critical applications.
Consider minor differences stemming from the US survey foot base for the chain unit.

Limitations

Aln length can vary historically and regionally, affecting conversion accuracy.
The US survey chain is based on the US survey foot, differing slightly from the international foot.
This conversion assumes standard unit definitions and may not apply to situations requiring very high precision or localized standards.
