How to convert megaparsecs to astronomical units
1 megaparsec is equal to 206,264,806,200 astronomical units, and 1 astronomical unit is equal to 4.848136811 × 10⁻¹² megaparsecs. To convert, multiply by the conversion factor:
astronomical units = megaparsecs × 206,264,806,200
astronomical units = megaparsecs ÷ 4.848136811 × 10⁻¹²Example: convert 1 Mpc to au: 1 × 206,264,806,200 = 206,264,806,200 au.
