What is Earth's equatorial radius?

It is the distance from Earth's center to the equator measured along the equatorial plane, standardized at 6,378.137 kilometers in the WGS84 reference system.

Why use nautical miles for navigation?

Nautical miles are based on a fixed meter length related to one minute of latitude and are used for measuring distances and speeds in marine and aeronautical contexts.

Can this tool convert other length units?

This tool specifically converts lengths from Earth's equatorial radius to international nautical miles based on established definitions.
