This action is mostly symbolic but as any American will point out the imperial system is actually more flexible and useful than metric which is plain awful. I have used SI for many years but prefer to think of atmospheric pressure as 14psi not 101,325 Pa. We all live between 0 to 100F. This equates to -18 to 38 Celsius. Granularity of 100 units compared to only 56. I go out and fire a pistol and the energy is 350ft lb. Something I can visualise not 474 joules. The key thing is imperial was created to help trade. Base 12 factorises with 1,2,3,4,6. Base 10 by 1,2,5 only. The old LSD currency factored massively. As a child I had to do addition, subtraction, multiplication and division of numbers consisting of up to three different bases in my head. Get it wrong and I got hit. What you had was a population who was numerate and literate to a degree unobtainable now. I have a Victorian maths book designed for 8 year olds. I showed it to some maths PHD students at my university and they were unable to answer the questions. Yes the PHD students would have failed the school exams in the late 1890s. Most people now cannot spell or count. Nursing staff reach for a calculator to divide 5 by 2, miss key and give multiple times the dose to a patient resulting in death. This does happen a lot but strangely is not usually reported. As for Brexit. Well a lot of people became very irrational in 2016 and did weird things on the FX markets. I was able to make enough money to retire six years early, and buy a house for cash. The UK should do very well going forward. Some people will remain irrational and lose out. personally I do not care it will be their financial funerals.

The imperial system is logical and actually much easier to use than metric. It needs a few brain cells but when mastered. Hey it's easy. I have used the metric system for years and found it contrived and awkward. Recently I have started using imperial units and there is a lot of history and logic behind it. OK NASA goes metirc. The French have won, Now repeat after me (hands in the air. I surrender, I surender, I surrender. Feeling French yet (dont worry it will come)). What's more accurate 1/32 of an inch or 1mm? What divides into 3, 4 and 6 better 12 or 10? What can you use the human body to make most measurements by metric or imperial? Never mind.
