Personally, I use the convention of measuring the length of
boats in feet and the beam in metres. :-)

I measure feet in toes. There are five toes to a foot.
I also measure gas and electricity in meters, never in metres.

Just remember inertial, when you look up at the stars and believe that
you are looking at objects that are millions of years into the past-
that you are the one who believes in sante claws.

moving faster than c. Phase velocity for one. But so far, no one has
ever demonstrated that information can be transmitted faster than c.
