What is a famn used for?

A famn is a traditional maritime length unit equivalent to one fathom, used mainly for depth measurement, specifying lengths of ship ropes, and interpreting historical maritime data.

What does Earth's polar radius represent?

Earth's polar radius is the distance from Earth's center to the average geographic pole along the rotation axis, corresponding to the semi-minor axis of a geodetic ellipsoid.

Why convert famn to Earth's polar radius?

This conversion helps relate maritime lengths to global scale measurements, enabling integration of nautical data with geodesy, cartography, and satellite information.

Browser-based and easy to use for professionals and enthusiasts alike

Examples

10 famn equals 10 times 2.8022586498368e-7 Earth's polar radius, or 2.8022586498368e-6 Earth's polar radius
1000 famn equals 1000 times 2.8022586498368e-7 Earth's polar radius, or 2.8022586498368e-4 Earth's polar radius

Common Use Cases

Documenting water depths on nautical charts with reference to Earth dimensions
Relating lengths of shipboard ropes or cables to geodetic distances
Converting historical maritime measurements for use in geospatial and satellite applications
Supporting mapping and satellite orbit modeling through standardized unit conversions

Tips & Best Practices

Ensure accurate input values for precise small-scale conversions
Verify the exact famn definition used regionally before converting
Use conversion results to integrate nautical data with global Earth models accurately
Consult geodetic references when applying conversions in mapping or satellite analyses

Limitations

Famn is small relative to Earth's polar radius, making output values very small
Regional differences in famn definitions can affect conversion accuracy
Earth's polar radius is based on an average geodetic parameter which may vary by ellipsoid model
