How to convert millimeters to atomic units of length
1 millimeter is equal to 18,897,261.25 atomic units of length, and 1 a.u. of length is equal to 5.291772109 × 10⁻⁸ millimeters. To convert, multiply by the conversion factor:
atomic units of length = millimeters × 18,897,261.25
atomic units of length = millimeters ÷ 5.291772109 × 10⁻⁸Example: convert 1 mm to a₀: 1 × 18,897,261.25 = 18,897,261.25 a₀.

About the millimeter
A millimeter is one thousandth of a meter. It's the standard unit in engineering drawings, manufacturing, rainfall and screen and paper sizes.
Symbol: mm · 1 mm = 0.001 m · Category: Metric (SI)
About the a.u. of length
The atomic unit of length is the Bohr radius, about 5.29 × 10⁻¹¹ m: the most probable distance between the proton and electron in a hydrogen atom.
Symbol: a₀ · 1 a₀ = 5.291772109 × 10⁻¹¹ m · Category: Atomic & physics
