How to convert megameters to X-units
1 megameter is equal to 9.979243174 × 10¹⁸ X-units, and 1 x-unit is equal to 1.00208 × 10⁻¹⁹ megameters. To convert, multiply by the conversion factor:
X-units = megameters × 9.979243174 × 10¹⁸
X-units = megameters ÷ 1.00208 × 10⁻¹⁹Example: convert 1 Mm to xu: 1 × 9.979243174 × 10¹⁸ = 9.979243174 × 10¹⁸ xu.

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 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.
