How to convert femtometers to astronomical units
1 femtometer is equal to 6.684587122 × 10⁻²⁷ astronomical units, and 1 astronomical unit is equal to 1.495978707 × 10²⁶ femtometers. To convert, multiply by the conversion factor:
astronomical units = femtometers × 6.684587122 × 10⁻²⁷
astronomical units = femtometers ÷ 1.495978707 × 10²⁶Example: convert 1 fm to au: 1 × 6.684587122 × 10⁻²⁷ = 6.684587122 × 10⁻²⁷ au.
