Try this example →Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
Mile (mi). The mile is 1,609.344 meters (5,280 feet), used for road distances in the US and the UK.
There are 5,878,625,373,184 miles in one light year.
Multiply the number of light years by 5,878,625,373,184. For example, 10 light years equal 58,786,253,731,836 miles.
One mile equals 1.70108 × 10⁻¹³ light years.
70,543,504,478,203 miles. Other common values: 5 light years = 29,393,126,865,918 miles and 100 light years = 587,862,537,318,361 miles.
