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