What Is This Tool?
This converter transforms length measurements from the international nautical mile unit to the US survey inch unit, helping users translate marine and aeronautical distances into legacy U.S. surveying units for various applications.
How to Use This Tool?
-
Enter the value in nautical mile (international) you wish to convert.
-
Select inch (US survey) as the target unit.
-
Click convert to see the equivalent length in inch (US survey).
Key Features
-
Converts from nautical mile (international) to inch (US survey) accurately based on defined conversion rate.
-
Supports understanding of legacy units commonly used in historical U.S. surveying and cadastral data.
-
Browser-based and user-friendly interface for quick and easy conversions.
Examples
-
2 nautical miles (international) converts to 145,826.48 inch (US survey) [in].
-
0.5 nautical miles (international) converts to 36,456.62 inch (US survey) [in].
Common Use Cases
-
Measuring distances between waypoints and routes on marine and aeronautical charts in legacy units.
-
Translating vessel and aircraft speeds for navigation and scheduling purposes.
-
Interpreting historical U.S. survey and cadastral records involving US survey inch units.
-
Processing older maps or survey datasets for engineering or geodetic analysis.
Tips & Best Practices
-
Use this converter primarily for legacy data or specialized surveying records requiring US survey units.
-
Cross-check converted results when integrating with modern international or metric data sets.
-
Be mindful that the US survey inch is a legacy unit less common in current surveying practices.
Limitations
-
The US survey inch is a legacy unit, mostly relevant only for historical data interpretation.
-
Modern surveying predominantly uses international feet or metric units, limiting this conversion’s general use.
-
There may be precision differences due to slight definition variances between US survey and international units.
Frequently Asked Questions
-
What is a nautical mile (international)?
-
It is a unit of length exactly defined as 1,852 meters, historically representing one minute of arc of latitude for measuring marine and aeronautical distances.
-
Why use inch (US survey) units?
-
The US survey inch is a legacy surveying unit used in historic U.S. geodetic control, cadastral surveys, and mapping datasets.
-
Can this tool convert modern measurements?
-
This tool is intended mainly for converting between the international nautical mile and legacy US survey inches, mostly for interpreting historical data.
Key Terminology

Nautical Mile (International)
-
A length unit exactly defined as 1,852 meters, used for marine and aeronautical navigation.
-
Inch (US Survey)
-
A legacy surveying unit equal to 1/12 of the US survey foot, used historically in U.S. geodetic and cadastral surveys.
-
Knot
-
A speed unit equivalent to one nautical mile per hour, used in navigation.
