How to convert megameters to light years
1 megameter is equal to 1.057000834 × 10⁻¹⁰ light years, and 1 light year is equal to 9,460,730,473 megameters. To convert, multiply by the conversion factor:
light years = megameters × 1.057000834 × 10⁻¹⁰
light years = megameters ÷ 9,460,730,473Example: convert 1 Mm to ly: 1 × 1.057000834 × 10⁻¹⁰ = 1.057000834 × 10⁻¹⁰ ly.

About the megameter
A megameter is one million meters (1,000 km). Earth's radius is about 6.4 Mm.
Symbol: Mm · 1 Mm = 1,000,000 m · Category: Metric (SI)
About the light year
A light-year is the distance light travels in a vacuum in one Julian year (365.25 days): about 9.46 trillion km. The nearest star system, Alpha Centauri, is about 4.37 light-years away.
