How to convert kilometers to light years
1 kilometer is equal to 1.057000834 × 10⁻¹³ light years, and 1 light year is equal to 9,460,730,473,000 kilometers. To convert, multiply by the conversion factor:
light years = kilometers × 1.057000834 × 10⁻¹³
light years = kilometers ÷ 9,460,730,473,000Example: convert 1 km to ly: 1 × 1.057000834 × 10⁻¹³ = 1.057000834 × 10⁻¹³ ly.
