What is a chain in measurement?

A chain is a traditional surveying length equal to 66 feet or approximately 20.1168 meters, historically used in land measurement.

How many miles are in one chain?

One chain equals 0.0125 miles based on the standard conversion rate.

Why convert chains to miles?

Converting chains to miles helps interpret historic land surveys in modern units commonly used in mapping and road distance measurements.

How to Convert from Chain [ch] to Mile [mi, mi(Int)]?

Learn how to convert length measurements from chain (ch), a traditional surveying unit, to mile (mi), an imperial unit for land distances. This guide covers definitions, use cases, and conversion examples.

What Is This Tool?

This online converter helps you change length measurements from chain, a historic unit used in land surveying, into miles, which are commonly used for road distances and mapping in imperial measurement regions.

How to Use This Tool?

Enter the length value in chains you want to convert.
Select 'chain [ch]' as the input unit and 'mile [mi, mi(Int)]' as the output unit.
Click convert to see the equivalent distance in miles.

Key Features

Converts length values between chains and miles using standard conversion rates.
Supports understanding of traditional surveying units in modern mapping contexts.
Browser-based tool that is easy to use without installation.

Examples

5 chains equals 0.0625 miles.
20 chains equals 0.25 miles.

Common Use Cases

Converting historic land survey measurements into modern units for land registration.
Interpreting old engineering and agricultural survey documents using imperial units.
Relating traditional cadastral measurements to road distances and mapping scales.

Tips & Best Practices

Ensure the chain values come from reliable historic or cadastral records for meaningful conversions.
Use the converter for land survey contexts or when integrating historic data with GIS.
Be cautious of potential small errors in original measurements when scaling to miles.

Limitations

Chains are mostly historical and less used in contemporary measurements.
Conversions may reflect inaccuracies due to old surveying methods.
Small input errors in chains may lead to larger discrepancies when shown in miles.
