How to convert atomic units of length to feet
1 a.u. of length is equal to 1.736145705 × 10⁻¹⁰ feet, and 1 foot is equal to 5,759,885,228 atomic units of length. To convert, multiply by the conversion factor:
feet = atomic units of length × 1.736145705 × 10⁻¹⁰
feet = atomic units of length ÷ 5,759,885,228Example: convert 1 a₀ to ft: 1 × 1.736145705 × 10⁻¹⁰ = 1.736145705 × 10⁻¹⁰ ft.
