What is Earth's polar radius?

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

What is a fathom and where is it used?

A fathom is a traditional English length unit equal to 6 feet (1.8288 meters), mainly used to measure water depths and rope lengths in nautical contexts.

Why convert Earth's polar radius to fathoms?

Converting helps translate large geodetic distances into familiar nautical units, aiding in maritime navigation and interpreting historical maritime documents.

Provides clear definitions and context for both units.
Includes practical examples for quick reference.
Browser-based and easy to use without installation.
Useful for maritime navigation and geodetic applications.

Examples

1 Earth's polar radius equals 3,475,927.93 fathoms.
0.5 Earth's polar radius converts to 1,737,963.96 fathoms.

Common Use Cases

Translating geodetic measurements into traditional nautical lengths for marine navigation.
Interpreting historical maritime records that use fathoms.
Supporting geodesy, satellite orbit modeling, and Earth shape analysis.
Converting geophysical data into units familiar to mariners.

Tips & Best Practices

Ensure accurate input values for reliable conversions.
Use the tool for large-scale measurements rather than small nautical depths.
Understand the context of each unit before applying conversions.
Apply results primarily in academic, navigational, or historical scenarios.

Limitations

Earth's polar radius is an extensive geodetic value rarely used in everyday nautical settings.
Fathoms are traditionally for smaller water depths, so applying them to large distances may be of limited practical value.
Conversion precision may surpass typical requirements used in navigation.
