Convert **femtonewton** to **atomic unit of force**

Selected category: force.

Femtonewton (fN) is a metric unit of force equal to 10^{-15} N, or 0,1 nanodynes.

Atomic units (au or a.u.) form a system of units convenient for atomic physics, electromagnetism, and quantum electrodynamics. Atomic unit of force is defined to be equal to E_{h}/a_{o}=8.238722241 x 10^{-8} N . (calculations are based on Hartree atomic units)
