A pole, also called rod or perch, is a traditional English length unit used in land surveying, equal to 16.5 feet or 5.0292 meters.

Where is the US survey fathom used?

The US survey fathom is used primarily in nautical and hydrographic settings to measure water depths and line lengths.

Why convert from pole to fathom (US survey)?

Converting helps integrate historical land measurement data with maritime or hydrographic measurements for accurate interdisciplinary analysis.

What Is This Tool?

This converter facilitates length conversions from the pole, a traditional English land measurement unit, to the US survey fathom, used primarily in nautical and hydrographic measurements. It supports interdisciplinary applications involving historical and modern measurement systems.

How to Use This Tool?

Enter the numeric value representing poles to convert.
Select 'pole' as the original unit and 'fathom (US survey) [fath]' as the target unit.
Submit the form to obtain the converted length in fathoms.
Use the result to interpret or integrate land-based length measurements into nautical contexts.

Key Features

Converts from pole (rod/perch) to US survey fathom accurately using official conversion rates.
Supports understanding of historical land distances and maritime depth measurements.
Browser-based and user-friendly interface for quick length unit conversions.
Useful for reconciling legacy land and hydrographic data within surveys and property records.

Examples

Convert 2 poles to fathoms: 2 × 2.7499945 = 5.499989 fathoms (US survey).
Convert 0.5 pole to fathoms: 0.5 × 2.7499945 = 1.37499725 fathoms (US survey).

Common Use Cases

Interpreting measurements from historical British and colonial property deeds.
Updating cadastral records by converting old survey measurements to modern units.
Understanding dimensions in historic agricultural or civil-engineering documents.
Recording and analyzing water depths or line lengths in nautical charts and hydrographic surveys.
Reconciling legacy hydrographic data with modern measurement standards.

Tips & Best Practices

Always verify which measurement system (international or US survey) is used to avoid unit confusion.
Use this converter primarily for historical or interdisciplinary surveying needs involving land and water measurements.
Consult original survey or nautical documentation to confirm unit usage and context before converting.
Remember the pole is mostly a historic unit, so conversions often apply to legacy data.

Limitations

The pole is an outdated and non-standard measurement unit rarely used today outside historical contexts.
The US survey fathom differs slightly from the international fathom, so conversions should consider this subtle discrepancy.
Mixing international and US survey units without caution may result in small inaccuracies.
