Miles to Astronomical Units

Mile

A mile (mi) is a well-known unit of length in the imperial system, equal to 5,280 feet or about 1.609 kilometers. It is commonly used in the United States and the United Kingdom to measure travel distances, road signs, running events, and property boundaries. The mile provides a practical scale for everyday movement and transportation.

Because much of the world uses kilometers, conversions between miles and metric units are frequently needed. A unit converter helps ensure quick and accurate results—whether planning a road trip or checking your workout distance.

Astronomical Unit

An astronomical unit (AU) is a standard space measurement based on the distance from the Earth to the Sun—about 149.6 million kilometers or 93 million miles. It helps describe solar system distances in practical numbers rather than extremely large values.

Astronomers use AU values to measure orbits of planets, asteroids, and comets relative to Earth.
