1 million miles is equal to 0.0000 light-years. This is because a light-year is an enormous distance (about 5.88 trillion miles).

The conversion is so small because light-years measure astronomical distances, while miles measure much smaller, everyday distances. The universe is incredibly vast!

A light-year is used by astronomers to measure the vast distances between stars and galaxies.

Yes, spacecraft have traveled millions of miles from Earth, but this distance is still extremely small compared to distances measured in light-years.
