What is a link [li] unit?

The link is a historic English length unit used mainly in 18th–19th century surveying, defined as 1/100 of Gunter's chain, approximately 0.201168 metres.

What does the megameter [Mm] represent?

A megameter is an SI-derived unit of length equal to one million metres (1,000,000 m), commonly used to express very large terrestrial or planetary distances.

Why would I convert from links to megameters?

Converting from links to megameters helps integrate historical land survey measurements into modern scientific or engineering contexts involving large-scale distances.

What Is This Tool?

This converter allows you to translate length values measured in the historic English unit called link [li] into the SI-derived megameter [Mm]. It supports users working with historical land survey data as well as those relating large distance measurements on scientific and engineering scales.

How to Use This Tool?

Enter the length value in links [li] you wish to convert.
Select 'link [li]' as the source unit and 'megameter [Mm]' as the target unit.
Click the conversion button to obtain the equivalent value expressed in megameters.

Key Features

Converts historic link units used in 18th–19th century surveying to modern megameters.
Provides an accessible way to relate small, historic length units to large-scale SI measures.
Browser-based tool that supports integration of old cadastral information with contemporary mapping and planetary data.

Examples

Convert 1000 links [li]: results in 0.000201168 megameters [Mm].
Convert 500,000 links [li]: equals 0.100584 megameters [Mm].

Common Use Cases

Understanding and interpreting historical land measurements in modern length units.
Reconstructing old property boundaries using archived survey records.
Describing large-scale distances in planetary science and regional geodesy.

Tips & Best Practices

Ensure source data pertains to the historic link unit as used in 18th–19th century surveying.
Remember that the link is a small unit, so converted megameter values will often be very small.
Use this converter primarily for academic, archival, or scientific purposes rather than everyday measurements.

Limitations

The link unit is no longer in common use and may vary slightly depending on historical surveying standards.
Conversions to megameters yield very small values, limiting practical use outside academic or archival contexts.
Precision may be affected by historical inconsistencies in the exact length of the link.
