What does femtometer per square second measure?

It measures acceleration based on extremely small distances, specifically velocity change at the scale of one femtometre (10⁻¹⁵ metre) per second each second.

Are femtometer/square second and kilometer/square second commonly used together?

They are generally used in different contexts—femtometer/square second for subatomic phenomena and kilometer/square second for astronomical or geophysical phenomena—so direct comparison is rare.
