# Kilometer (km) to Light year (ly)

Units of length ﹣ Converter Kilometer to Light year

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

The unit kilometer belongs to the metric system and is derived from the basic unit meter. Here, 1 kilometer can be converted into 1,000 meters or 1 meter is equivalent to 0.001 kilometers. The kilometer belongs to the International System of Units (SI).

In most parts of the world today, kilometers is the measuring unit used to express distances between geographical locations in the countryside. The United States and the United Kingdom are exceptions to this practice, where miles are used as a measuring unit.

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.
