What is a nautical league (int.)?

It is a historical maritime length unit equal to 3 international nautical miles or 5,556 metres, used to express sea distances.

Why convert nautical leagues to inches (US survey)?

To translate historical maritime distances into legacy surveying units for integrating old maritime data with land records and maps.

Is the US survey inch still used today?

The US survey inch is largely replaced by the international inch but is still relevant for interpreting historical surveying and cadastral data.

Supports interpretation of historical maritime and surveying data.
Useful for archival research, map restoration, and legacy dataset integration.
Browser-based and easy to operate without specialized software.

Examples

2 nautical leagues (int.) converts to 437,479.44 inch (US survey).
0.5 nautical league (int.) converts to 109,369.86 inch (US survey).

Common Use Cases

Interpreting distances on historical nautical charts and sailing logs from the 18th and 19th centuries.
Converting maritime measurements into SI units or surveying units for archival or scholarly research.
Processing and updating legacy U.S. survey and cadastral records involving US survey units.
Integrating old maritime distance data with land survey maps in engineering projects.

Tips & Best Practices

Verify the historical context to ensure the appropriate unit definitions are used.
Use the tool primarily for archival, legal, or scholarly projects involving legacy measurements.
Consider modern unit standards when applying converted data to current surveying work.
Cross-check conversions when precision is critical due to rounding or definition variations.

Limitations

Both units are historical or legacy and may have inaccuracies from rounding or definition inconsistencies.
US survey inch has been mostly replaced by the international inch in modern surveying.
Conversion is mainly useful for historical or archival data rather than current practical measurements.
