To convert Mm to km: multiply by 1,000. To convert Mm to miles: multiply by 621.371.
1 Mm = 10⁶ m = 1,000 km = 1,000,000 m.
For example, 1 Megameter (Mm) = 3.240756e-14 Kiloparsec (kpc).

The megameter is a unit of length equal to 10⁶ meters (1,000 kilometers or one million meters).
1 Mm = 10⁶ m = 1,000 km = 1,000,000 m.
To convert Mm to km: multiply by 1,000. To convert Mm to miles: multiply by 621.371.
Describing planetary diameters and distances within the solar system in a compact metric form.
Earth's diameter ≈ 12.7 Mm. The circumference of Earth ≈ 40 Mm — this is by design, as the meter was originally defined from it.
Uppercase matters: 'Mm' = megameter (10⁶ m), 'mm' = millimeter (10⁻³ m) — a factor of 10⁹ difference!
Remember the SI prefix pattern: kilo (10³), mega (10⁶), giga (10⁹). Each step is 1,000× larger.
The kiloparsec is equal to 1,000 parsecs, approximately 3,262 light-years, used for measuring distances within galaxies.
1 kpc = 1,000 pc = 3,261.6 ly = 3.0857 × 10¹⁹ m.
To convert kpc to light-years: multiply by 3,261.6. To convert kpc to pc: multiply by 1,000.
Mapping spiral arm structures, locating star clusters, and describing galactic halo dimensions.
The Milky Way disk is about 30 kpc in diameter. The Sun orbits the galactic center at a distance of ~8.2 kpc.
Forgetting the factor of 1,000: 1 kpc = 1,000 pc, not 100 pc.
Think of kpc as the 'kilometer' of galaxy mapping — most features within a galaxy are measured in kpc.
