What is a nautical mile (international)?

It is a length unit defined as exactly 1,852 meters, historically equal to one minute of arc of latitude on Earth and used primarily for marine and aeronautical navigation.

What does Earth's equatorial radius represent?

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

Why convert nautical miles to Earth's equatorial radius?

This conversion helps express navigation distances relative to a fundamental Earth measurement, aiding geodetic, cartographic, and aerospace applications.

Tips & Best Practices

Use this tool for comparative or scaling purposes rather than direct distance substitution.
Remember that the conversion is based on the WGS84 equatorial radius standard and does not account for local variations.
Ensure unit selections are correct to avoid conversion errors.
Refer to example calculations to verify your own conversions.

Limitations

The conversion relies on a fixed equatorial radius value from the WGS84 ellipsoid standard.
Local variations in Earth's radius due to topography or geoid shape are not considered.
Nautical miles represent linear distances while Earth's equatorial radius is a constant planetary dimension.
Conversion is mainly useful for relative scale comparisons and geodetic referencing, not direct measurement substitution.
