Sorry, but for the avoidance of confusion, you are thirty years out of
date.  Since 1983, the metre has been defined as the distance
travelled by light _in vacuo_ in a specified time.  This has the
effect of *defining* the value of the speed of light, of course.

It's still tied to a physical constant.  Now, what's the speed of dark? ;-)
