What Is This Tool?
This tool allows you to convert length values from micrometers (µm), an SI-derived unit used at microscales, to the historic English unit of length called link (li), which was commonly used in surveying and land measurement.
How to Use This Tool?
-
Enter the length value in micrometers (µm) you wish to convert.
-
Select micrometer as the input unit and link as the output unit.
-
Click convert to see the corresponding length value in links (li).
Key Features
-
Converts micrometer values to link units accurately based on established conversion rates.
-
Supports understanding of both modern microscale and historical surveying measurement units.
-
Browser-based and easy to use without installation.
Examples
-
100 micrometers (µm) equals approximately 0.000497097 links (li).
-
1,000 micrometers (1 millimeter) is about 0.00497097 links.
Common Use Cases
-
Converting scientific microscale measurements into historical surveying units for comparison.
-
Interpreting and digitizing old land measurement and cadastral records that use links.
-
Reconstructing historical property boundaries from archival documents.
Tips & Best Practices
-
Double-check input values for micrometer measurements to ensure accurate conversion results.
-
Use the tool primarily for historical or research purposes involving legacy land measurement data.
-
Be mindful of the small fractional results when converting tiny micrometer values to links.
Limitations
-
The link is an obsolete unit not used in current measurement systems, limiting practical applications.
-
Conversions of very small micrometer values result in tiny fractions that may have limited relevance.
-
Possible rounding effects can affect precision when relating modern and historical units.
Frequently Asked Questions
-
What is a micrometer used for?
-
A micrometer is used to measure dimensions at a very small scale, such as the size of microorganisms, thickness of coatings, or features in microdevices.
-
Where was the link unit commonly used?
-
The link was historically used in English land surveying, especially in 18th and 19th-century cadastral records and property measurements.
-
Why convert micrometers to links?
-
Converting micrometers to links helps relate precise modern measurements to historical surveying units found in old land records and maps.
Key Terminology
-
Micrometer (µm)
-
An SI unit of length equal to one millionth of a meter, used to measure very small dimensions.
-
Link (li)
-
A historic English unit of length used in surveying, equal to 1/100 of Gunter's chain or approximately 0.201168 meters.
-
Gunter's Chain
-
A measuring device used historically in land surveying, consisting of 100 links per chain.
