How to convert light years to gigameters
1 light year is equal to 9,460,730.473 gigameters, and 1 gigameter is equal to 1.057000834 × 10⁻⁷ light years. To convert, multiply by the conversion factor:
gigameters = light years × 9,460,730.473
gigameters = light years ÷ 1.057000834 × 10⁻⁷Example: convert 1 ly to Gm: 1 × 9,460,730.473 = 9,460,730.473 Gm.
