LOL!
Then avert your eyes around the video world with it's 1/2", 2/3", and 1" sensors. Worse than being non-metric, those standard dimensions are defined by the
diameter of the vacuum tube that would be required to house the vidicon/plumbicon/saticon video circuits!
P.S. I once flummoxed a fellow engineer and devoted proponent of the Imperial system by trying to get him to explain the difference between pounds-force and pounds-mass.
