What is a nautical mile (international)?

It is a unit of length defined exactly as 1,852 meters, primarily used for measuring marine and aeronautical distances.

What does one light year represent?

A light year is the distance light travels in a vacuum over one Julian year, approximately 9.4607 × 10^15 meters.

Why convert nautical miles to light years?

The conversion helps compare familiar Earth-based navigation distances to the vast scales used in astronomy and space exploration.
