The imperial system was defined in 1824 (befoee that a mile was very different depending in the Region you came Form) The metric system was first defined in 1793... Imperial was never 'good for its time' cause it is actually younger than metric .

Yes it dies habe Mord historical baggage (Roman and stuff) but that doesnt mean the system itself is old. The old meassurements eere just local customs and not a system - what a 'foot' was actually differed depending in where you Where which is amazingly Bad for a meassurement .

Fahrenheit is actually a hilariously Bad design : first the original meassurements cant be reproduced (or rather: Fahrenheits meassurements were imprecice) Second : it has three points defined - you only need two - three Pointe just makes everything More momplicated Only one positiv thing here: dude was the first to create a halfway decent temperature unit
