What Is This Tool?

This tool allows you to convert measurements from Earth's polar radius, a geodetic length representing the distance from Earth's center to the mean geographic pole, into the US survey fathom unit used in nautical contexts.

How to Use This Tool?

  • Enter the value in Earth's polar radius units you want to convert.
  • Select the target unit as fathom (US survey) [fath].
  • Click the convert button to get the result in fathoms (US survey).

Key Features

  • Converts Earth's polar radius values to fathom (US survey) units accurately based on defined conversion rates.
  • Supports key use cases in geodesy, satellite orbit modelling, hydrographic surveying, and maritime navigation.
  • Online and easy to use with simple input fields and clear output results.

Examples

  • 1 Earth's polar radius equals 3,475,920.9790277 fathoms (US survey).
  • 0.5 Earth's polar radius converts to 1,737,960.48951385 fathoms (US survey).

Common Use Cases

  • Defining the semi-minor axis of geodetic ellipsoids like WGS84 for mapping and GPS applications.
  • Modelling satellite orbits and interpreting satellite altimetry data.
  • Relating large geodetic reference measurements to nautical lengths in maritime navigation and hydrographic surveys.
  • Converting legacy hydrographic survey data recorded in US survey fathoms to metric units.

Tips & Best Practices

  • Verify unit consistency when working with US survey fathoms versus international fathoms due to slight differences.
  • Use this conversion primarily for integrating earth-shape data with nautical charts and legacy survey records.
  • Be cautious when interpreting measurements since Earth's polar radius is very large and may not suit all practical maritime applications.

Limitations

  • Earth's polar radius is extremely large and not generally used for direct fathom measurements in maritime contexts.
  • The US survey fathom is not identical to the international fathom, requiring careful unit handling.
  • Legacy survey data in US survey units may include rounding or definition differences compared to metric standards.

Frequently Asked Questions

What is Earth's polar radius?
Earth's polar radius is the distance from Earth’s center to the mean geographic pole along the rotation axis, representing the semi-minor axis of a reference ellipsoid like WGS84.

What is a fathom (US survey)?
A US survey fathom is a nautical length unit equal to exactly 6 US survey feet, used primarily in hydrographic surveys and maritime measurements.

Why convert Earth's polar radius to fathoms (US survey)?
Converting these units helps relate large geodetic measurements to nautical length units for integrating earth-shape data with historical nautical charts and maritime navigation.

Key Terminology

Earth's polar radius
The distance from Earth's center to the mean geographic pole along the rotation axis, used as the semi-minor axis in geodetic ellipsoids.
Fathom (US survey) [fath]
A non-SI nautical length unit equal to 6 US survey feet, used for measuring depths and line lengths in hydrography.
WGS84
A widely used geodetic reference ellipsoid representing Earth's shape, defining Earth’s polar radius.
