One could easily spend more time trying to measure 1.905 cm vs very quickly dividing 1 into 3/4".
If the standard is written in Metric, the factory that makes the parts uses metric, and the place where the parts are used uses metric, why don’t they just use 2cm screws instead?
Your argument for the convenience of imperial is that the standard uses imperial. No shit. It would be just as hard to cut something to 0.787" inches if the standard were in metric.
Also the reason metric makes more sense is I don’t need a calculator to convert centimeters to kilometres. You need a calculator to convert inches to miles. AND you have to memorise the conversion factor! What a waste of brainpower
