What is a fathom used for?

A fathom is traditionally used to measure water depth, lengths of ropes, and cables in nautical settings.

How is Earth's equatorial radius defined?

It is the distance from Earth's center to the equator along the equatorial plane, standardized as 6,378.137 kilometers.

Why convert fathoms to Earth's equatorial radius?

This conversion helps relate traditional nautical distances to planetary scale measurements for geodesy, Earth sciences, and satellite applications.

What Is This Tool?

This unit converter allows you to transform measurements given in fathoms, a traditional English length unit mostly used in nautical contexts, into Earth's equatorial radius, which is a key planetary scale distance used in geodesy and Earth sciences.

How to Use This Tool?

Enter the measurement value in fathoms into the input field
Select 'fathom [fath]' as the source unit and 'Earth's equatorial radius' as the target unit
Initiate the conversion to get the equivalent value expressed in Earth's equatorial radius

Key Features

Converts length from fathoms to Earth's equatorial radius using an accurate conversion factor
Supports applications in nautical navigation, geodesy, aerospace engineering, and Earth science
Browser-based, easy-to-use interface for quick conversions
Includes example conversions for reference

Examples

Converting 10 fathoms results in 2.8672846087273e-6 Earth's equatorial radius
1000 fathoms equals 0.00028672846087273 Earth's equatorial radius

Common Use Cases

Expressing traditional nautical depth data in terms of a planetary radius
Integrating maritime measurements with global geodetic reference frameworks
Supporting calculations in satellite orbit determination and ground track modeling
