I'm wondering what other monstrous metric-English combinations are out
there?


Car tyres have metric width and imperial rim diameter. Except some
(rare) American(!) rims, which have metric diameter.

Not just American rims, some european cars have metric diameter rims and
you better check the price of the tyres before you buy the car. Often 3
to 4 times the price of comparably sized inch tyres in the UK. Most
often it can be cheaper here to buy 4 new wheels and tyres in inch size
than to buy 4 metric tyres.


I have heard that the Italian model engine manufacturer Super Tigre
used to use bearings with metric outside diameter and imperial inside
diameter. I have never seen a bearing like that myself, though, so I
can't vouch for the accuracy of this.

Computer monitor size is measured in inches, while the pixel
resolution (dot pitch) is measured in millimeters.
