Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
There are 1.057 × 10⁻¹³ light years in one kilometer.
Multiply the number of kilometers by 1.057 × 10⁻¹³. For example, 10 kilometers equal 1.057 × 10⁻¹² light years.
One light year equals 9,460,730,472,581 kilometers.
1.057 × 10⁻¹⁰ light years. Other common values: 100 kilometers = 1.057 × 10⁻¹¹ light years and 10,000 kilometers = 1.057 × 10⁻⁹ light years.
