Annoyingly, though, metric cutting speeds are quoted in m/min which
introduces a pointless sexagesimal unit into all calculations.
Though given that we

As an American engineer, I almost invariably convert my "real world"
units into the metric system, solve the problem, and then translate the
solution back into the units that are used in my country. Cumulatively,
it's a significant competitive disadvantage for a nation, but it's
easier than

In the UK we buy milk by the litre. Either 0.568litres, 1.13 litres or 3.408

Yes, people who complain about the metric system apparently don't realize
that they are using it without even knowing it. The United States adopted
the metric standard for the inch in 1959.
All of our customary units are now defined in terms of the metric system.
The call is coming from inside

And by the way, (maybe already mentioned?), the inch used to vary in length
until it was defined as a function of the metre.
So the Americans are working in metric, but converted by 2.54 ...

Reducing metric to a decimal system only,is missing the point.
The metric system is BASE TEN. An important distinction from imperial.
The units of both metric and imperial could be considered arbitrary as
