What Is This Tool?
This tool converts length measurements from famn, a traditional maritime unit, to the US survey link, a historical land surveying unit. It helps reconcile nautical and land survey data for mapping, engineering, and historical analysis.
How to Use This Tool?
-
Enter the numeric value in famn units you wish to convert
-
Select famn as the input unit and link (US survey) [li] as the output unit
-
Click the convert button to get the equivalent measurement
-
Use the results for mapping, engineering, or historical research
Key Features
-
Converts famn to link (US survey) [li] based on historical standards
-
Supports integration of maritime and land survey measurements
-
Browser-based and easy to use without installation
-
Provides clear conversion examples
-
Assists with historical and cadastral data interpretation
Examples
-
2 famn equals approximately 17.71 link (US survey) [li]
-
5 famn equals approximately 44.27 link (US survey) [li]
Common Use Cases
-
Recording and interpreting water depths in nautical charts
-
Specifying shipboard rope or cable lengths
-
Analyzing historical maritime and coastal survey documents
-
Converting distances from historic US land survey plats
-
Reconciling legacy survey records in cadastral mapping
-
Supporting civil engineering projects involving old survey data
Tips & Best Practices
-
Verify conversions carefully when working with recent survey data
-
Be aware of differences between US survey feet and international feet
-
Use converted values to assist in integrating maritime and land measurements
-
Consult historical context to ensure unit appropriateness
-
Double-check final values to minimize rounding discrepancies
Limitations
-
Potential rounding errors due to differing maritime and land unit definitions
-
Link (US survey) is a historical unit not commonly used in modern surveys
-
Conversions may require validation when applied to current data
-
Possible confusion between US survey feet and international feet affects related units
Frequently Asked Questions
-
What is a famn unit used for?
-
A famn is a traditional maritime unit of length used mainly for recording water depths and specifying shipboard rope lengths.
-
Why convert famn to link (US survey) [li]?
-
Converting famn to link (US survey) [li] helps integrate maritime measurements with historic US land survey data for accurate mapping and analysis.
-
Can I use this tool for modern surveying data?
-
Since the link (US survey) is a historical unit, conversions should be carefully verified when applied to modern data.
Key Terminology
-
Famn
-
A traditional maritime length unit equal to one fathom (6 feet or 1.8288 meters), used for depths and nautical measurements.
-
Link (US survey) [li]
-
A historical unit of length equal to 1/100 of a Gunter's chain (0.66 US survey feet), used in US land surveying.
-
Gunter's chain
-
A measuring device used historically in land surveying, consisting of 66 US survey feet divided into 100 links.
