How to convert picometers to X-units
1 picometer is equal to 9.979243174 X-units, and 1 x-unit is equal to 0.100208 picometers. To convert, multiply by the conversion factor:
X-units = picometers × 9.979243174
X-units = picometers ÷ 0.100208Example: convert 15 pm to xu: 15 × 9.979243174 = 149.6886476 xu.

About the picometer
A picometer is 10⁻¹² meters. It's used for atomic and ionic radii and bond lengths; a hydrogen atom is about 50 pm across.
Symbol: pm · 1 pm = 1 × 10⁻¹² 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.
Symbol: xu · 1 xu = 1.00208 × 10⁻¹³ m · Category: Atomic & physics
