What is a link (li) unit?

A link (li) is a historic English unit of length used in surveying, equal to 1/100 of Gunter's chain or 0.201168 metres.

What is a micrometer (µm)?

A micrometer (µm) is an SI-derived unit of length equal to one millionth of a metre, used for measuring microscale dimensions.

Why convert link to micrometer?

Converting link to micrometer helps interpret historical land measurements in modern scientific units, aiding precise analysis and record restoration.

Can I use this conversion for everyday measurements?

Due to the different scales involved, this conversion is mainly suitable for archival, academic, or scientific interpretation rather than everyday use.

Is the link still used today?

The link is largely an obsolete unit, primarily found in historical records and land surveying documents from the 18th and 19th centuries.

Integrating historical data into geographic information systems (GIS).

Tips & Best Practices

Always check the historical context when interpreting link measurements.
Use this conversion primarily for archival, academic, or analytical purposes.
Remember that link units represent larger distances than micrometers, so apply conversions meaningfully.
Ensure consistent units when combining historical and modern measurement data.

Limitations

The link is a non-SI historic unit and not commonly used in current practice.
Micrometers measure microscale lengths, much smaller than links, limiting direct practical comparisons.
Conversion accuracy depends on the precision of original link measurements and may involve rounding.
