How to convert millimeters to light years
1 millimeter is equal to 1.057000834 × 10⁻¹⁹ light years, and 1 light year is equal to 9.460730473 × 10¹⁸ millimeters. To convert, multiply by the conversion factor:
light years = millimeters × 1.057000834 × 10⁻¹⁹
light years = millimeters ÷ 9.460730473 × 10¹⁸Example: convert 1 mm to ly: 1 × 1.057000834 × 10⁻¹⁹ = 1.057000834 × 10⁻¹⁹ ly.
