Oh how simple things would be if we all used metric (just ask NASA!).

Yes, the non-metric system has many disadvantages!

Machines that are manufactured for the USA or sold to Europe from there require different manufacturing machines and other tools. This makes these devices very expensive.

There have also been serious accidents. A Boeing crashed in the USA because gallons were mistaken for liters when checking fuel.

The first Ariane 4 had to be blown up because metric and non-metric values ​​were incorrectly implemented in the flight control system.

Another major confusion is that the USA not only uses inches for thread of screws, but also use other flank angles. An English inch screw does not fit on an American nut!


But we stray away from the topic. I am not entitled to politicize here.
