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