How to convert megaparsecs to X-units
1 megaparsec is equal to 3.079272694 × 10³⁵ X-units, and 1 x-unit is equal to 3.24752011 × 10⁻³⁶ megaparsecs. To convert, multiply by the conversion factor:
X-units = megaparsecs × 3.079272694 × 10³⁵
X-units = megaparsecs ÷ 3.24752011 × 10⁻³⁶Example: convert 1 Mpc to xu: 1 × 3.079272694 × 10³⁵ = 3.079272694 × 10³⁵ xu.

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).

About the x-unit
The X-unit (about 1.002 × 10⁻¹³ m) was used to express X-ray and gamma-ray wavelengths before the ångström and picometer became standard.
