How to convert barleycorns to atomic units of length
1 barleycorn is equal to 159,996,811.9 atomic units of length, and 1 a.u. of length is equal to 6.250124538 × 10⁻⁹ barleycorns. To convert, multiply by the conversion factor:
atomic units of length = barleycorns × 159,996,811.9
atomic units of length = barleycorns ÷ 6.250124538 × 10⁻⁹Example: convert 1 barleycorn to a₀: 1 × 159,996,811.9 = 159,996,811.9 a₀.
