How to convert X-units to atomic units of length
1 x-unit is equal to 0.001893656755 atomic units of length, and 1 a.u. of length is equal to 528.078807 X-units. To convert, multiply by the conversion factor:
atomic units of length = X-units × 0.001893656755
atomic units of length = X-units ÷ 528.078807Example: convert 15 xu to a₀: 15 × 0.001893656755 = 0.02840485132 a₀.

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.
