How to convert megaparsecs to kilometers
1 megaparsec is equal to 3.085677581 × 10¹⁹ kilometers, and 1 kilometer is equal to 3.240779289 × 10⁻²⁰ megaparsecs. To convert, multiply by the conversion factor:
kilometers = megaparsecs × 3.085677581 × 10¹⁹
kilometers = megaparsecs ÷ 3.240779289 × 10⁻²⁰Example: convert 1 Mpc to km: 1 × 3.085677581 × 10¹⁹ = 3.085677581 × 10¹⁹ km.

About the megaparsec
A megaparsec is one million parsecs (about 3.26 million light-years). It's used for distances between galaxies and in the Hubble constant (km/s/Mpc).
Symbol: Mpc · 1 Mpc = 3.085677581 × 10²² m · Category: Astronomical
About the kilometer
A kilometer is 1,000 meters. It's the standard unit for distances between places, road signs and running races in most countries.
Symbol: km · 1 km = 1,000 m · Category: Metric (SI)
