Yes we all agree that the metric system is in wide use in the US and that it was decided in 1975 that the US should go metric:
Metric Conversion Act was signed on December 23, 1975, by President Gerald R. Ford.
IFAIK it was also decided that the metric system should be taught in US schools
I can’t vouch for it being correct, but I remember hearing/seeing/reading somewhere that Ronald Reagan stated that he didn’t like the metric system because; “it is so difficult to remember all those conversions” (1" = 2.54 cm. 1 lbs = 454 g. etc.)
PS> He didn’t cancel the Act, just did not implement it fully.
It is also well know that “dollar divided into 100 cents” was the first use of metrics in any monetary system.
Correction:
Ronald Reagan did try, but only succeeded in abolishing the Metric Board that was tasked to work out how to implement it:
The Metric Board was abolished in 1982 by President Ronald Reagan, largely on the suggestion of Frank Mankiewicz and Lyn Nofziger.
