How to convert atomic units of length to centimeters
1 a.u. of length is equal to 5.291772109 × 10⁻⁹ centimeters, and 1 centimeter is equal to 188,972,612.5 atomic units of length. To convert, multiply by the conversion factor:
centimeters = atomic units of length × 5.291772109 × 10⁻⁹
centimeters = atomic units of length ÷ 188,972,612.5Example: convert 1 a₀ to cm: 1 × 5.291772109 × 10⁻⁹ = 5.291772109 × 10⁻⁹ cm.
