About these units

Miles

A mile (symbol: mi or m) is a unit of length commonly used in the United States and the United Kingdom. One mile is equal to 1.60934 kilometers.

The mile originated from the Roman mile, which was 1,000 paces. The current definition of a mile is based on the international agreement and equals exactly 1,609.344 meters.

Miles are mainly used to measure distances in the United States and the United Kingdom, especially for road systems. While most of the world uses kilometers, the mile remains prevalent in these countries.

Lightyears

A light-year is a unit of length used in astronomy to measure vast distances. One light-year is equivalent to approximately 9.461 trillion kilometers or about 5.879 trillion miles.

A light-year is defined by the distance that light travels in a vacuum in one year, which is about 9.461 × 10^12 kilometers.

Light-years are used to measure distances between stars, galaxies, and other celestial objects. They provide a convenient way to express astronomical distances, making it easier to understand the scale of the universe.
