# Conversion from Light year (ly) to Mile (mi) and vice versa

Updated on by Stefan Banse

Here you can convert the Unit of length Light year into the unit Mile and vice versa you can convert Mile into Light year. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result, i.e., ly to mi or mi to ly. With the following calculator you can also calculate any other Unit of length.

A light-year refers to the distance of light (in a vacuum) within one year. There are different definitions for a year (Gregorian year, tropical year, Julian year etc.), therefore the Julian year (365.25 days) was used as a definition for the light year. A light-year is converted to 9,460,730,472,580.8 km, around 9.5 trillion km. For example, the Milky Way is 100,000 light-years long because distance is difficult to measure in kilometers.

The mile is very common in the Anglo-American countries, but does not belong to the international unit system SI (Système international d'unités).

The term Mile originated during the Roman Empire as a sequence of 1,000 double steps, or mille passus (thousand steps). Nowadays a distinction is made between the land mile described here and the sea mile described in nautical studies. Therefore, 1 mile is equivalent to 1.609344 kilometers or 1 kilometer is equivalent to 0.62137 miles.
