What is Earth's polar radius?

Earth's polar radius is the distance from Earth's center to the geographic pole along the rotation axis, representing the semi-minor axis of the reference ellipsoid.

What does famn measure?

Famn is a maritime unit equivalent to one fathom, used to measure depths and nautical distances, traditionally equaling 1.8288 metres.

Why convert Earth's polar radius to famn?

Converting to famn helps translate large geodetic measurements into maritime units useful for nautical charting, historical surveying, and maritime navigation.

Common Use Cases

Converting geodetic Earth measurements to maritime units for nautical charting
Interpreting depths and distances in historical maritime surveying records
Supporting satellite orbit modelling and Earth-shape studies in compatible units

Tips & Best Practices

Use the tool to gain conceptual insight into the relationship between Earth's scale and maritime measurements
Apply conversions primarily for interpretive, educational, or comparative purposes due to scale differences
Verify unit definitions when working with historical maritime data where famn length might vary

Limitations

Significant scale difference limits practical application to conceptual comparisons
Historical variations in famn length may introduce precision issues
Earth's polar radius is fixed and geodetic, while famn is traditional and maritime, so conversions serve mainly interpretive needs
