How to convert meters to atomic units of length
1 meter is equal to 18,897,261,250 atomic units of length, and 1 a.u. of length is equal to 5.291772109 × 10⁻¹¹ meters. To convert, multiply by the conversion factor:
atomic units of length = meters × 18,897,261,250
atomic units of length = meters ÷ 5.291772109 × 10⁻¹¹Example: convert 1 m to a₀: 1 × 18,897,261,250 = 18,897,261,250 a₀.

About the meter
The meter is the SI base unit of length. Since 1983 it has been defined as the distance light travels in a vacuum in 1/299,792,458 of a second. It's used for everyday measurement almost everywhere in the world.
Symbol: m · 1 m = 1 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
