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

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.
