Kilometers to Light-years Converter

1 kilometer (km) equals 1.0570008 × 10-13 light-years (ly).

Quick answer

  • 1 kilometer = 1.0570008 × 10-13 light-years
  • 1 light-year = 9,460,730,473,000 kilometers
  • Formula: ly = km × 1.0570008 × 10-13

1 kilometer = 1.0570008 × 10-13 light-years

How to convert kilometers to light-years

ly = km × 1.0570008 × 10-13

To convert kilometers to light-years, multiply the number of kilometers by 1.0570008 × 10-13.

Example: 18 km to ly

  1. Start with the value in kilometers: 18 km.
  2. Multiply by 1.0570008 × 10-13: 18 × 1.0570008 × 10-13 = 1.9026015 × 10-12.
  3. Result: 18 kilometers = 1.9026015 × 10-12 light-years.

Going the other way, 1 light-year = 9,460,730,472,580 kilometers, so to convert light-years back to kilometers you divide by the same number. See light-years to kilometers.
