Why are physicians generally huge jerks?

Trade and labelling. See also the time NASA blew up a massively expensive rocket over an imperial/metric mismatch, or the disaster that was the US model of the Chauchat gun.

Also, I guarantee any medical care in the US is handled in metric. "Give me 5 ccs, stat" = 5 cubic cm, aka a "mil" or milliliter.

The Imperial system is already defined using the metric system for compatibility.
