How to convert kilometers to atomic units of length
1 kilometer is equal to 18,897,261,250,000 atomic units of length, and 1 a.u. of length is equal to 5.291772109 × 10⁻¹⁴ kilometers. To convert, multiply by the conversion factor:
atomic units of length = kilometers × 18,897,261,250,000
atomic units of length = kilometers ÷ 5.291772109 × 10⁻¹⁴Example: convert 1 km to a₀: 1 × 18,897,261,250,000 = 18,897,261,250,000 a₀.

About the kilometer
A kilometer is 1,000 meters. It's the standard unit for distances between places, road signs and running races in most countries.
Symbol: km · 1 km = 1,000 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
