  Tyvm, this is super handy! More precisely, ~1.01670 ns/ft (~0.983571 ft/ns).

    1ns = 300mm (or 30cm) 1us = 300m 1ms = 300km

  Just to be pedant, c is the speed of a photon in a vacuum. Electrons are much heavier and are traveling in a medium, copper. [0] https://en.wikipedia.org/wiki/Drift_velocity https://en.wikipedia.org/wiki/Drift_velocity

    The signal speed has nothing to do with the electrons’ drift velocity. It is a bit slower than c, but negligibly so.
