A light-second is a unit of length. It is defined as the distance light travels in an absolute vacuum in one second or 299,792,458 meters. Note that this value is considered exact, since the meter is actually (as of 1983) defined in terms of the light second. It is just over 186,282 miles and almost 109 feet.

Definition: Femtometre

The SI prefix "femto" represents a factor of
10^{-15}, or in exponential notation, 1E-15.

So 1 femtometre = 10^{-15} metre.
