I work in aviation and we use knots, Mach, feet, nautical miles, statute miles, meters, liters, US gallons you name it. A right mess!

Would a true Metric devotee really be comfortable with 0.1” [or indeed 2.54mm] lead spacing on components ?

Metric time didn’t work out very well either.

Base 60 for minutes in an hour and 24 for hours in a day was invented by the Babylonians some thousands of years BC, so I wouldn't call it Imperial

And yes I'm perfectly happy with 0.1" spacing on ICs, it's a world standard. No doubt in the Imperial nirvana some want to return to it will be changed to 1/8", can't have any of those nasty decimals can we

I've got some veroboard based on a 5/32" grid, so can we have ICs on that, rather than 1/8" please? It will make prototyping so much easier.

Incidentally, as far as I know, the only international unit defined in British units (rather than metric) was the Russian sagène which was defined in 1833 as seven English feet. It didn't last long.

The worlds most staunch supporter of the Imperial System, the USA, was I believe in fact the first country to adopt the Metre Standard in the late 1800’s, so why their reluctance of the metric system ?

For example, force is often measured in foot-pounds, or ounce inches,

It is ?

No it's not!

For the avoidance of doubt, Energy is measured in foot-pounds.

Think I should start a new thread for recording my mistakes. It shall be entitled: "What's the Clown Done Now?"
