As someone who hates this God forsaken measuring system, I genuinely don't know if the costs of this would ever be worth it. There'd be thousands and thousands of miles marker signs that'd have to be replaced, not to mention having to redo thousands of textbooks.
Plus, when it comes to some things, imperial is just better. Mostly this is carpentry. 12 is way more divisible than 10 and fractions are way easier for cutting than decimal
It would very much be worth it. Imperial invites mistakes by using weird conversions and factional sizes. I often have to stop and think which factions of an inch are bigger or smaller than each other. When Australia switched from imperial to metric, it's estimated they save about 10% annually from having a lower error rate. Fewer things need to get fixed or replaced from measurement mistakes.
A kitchen-scale example: I once mixed up tablespoons and teaspoons when adding baking soda to my pancake mix. They turned out disgusting and we had to re-make breakfast because version 1 was inedible. Such mistakes are less likely to happen under metric.
Eeeh... We have tablespoon (15ml) and teaspoon (5ml) here too....
The UK did this.
It's absolutely worth it. If you are worried about textbooks staying in circulation for a long time especially in 2024 then you got bigger issues to be honest.
Can't we just have both, and teach both? But like, in a more committed fashion than we currently do. Probably swapping out road signs and textbooks as they naturally need to be swapped out, to include both sets of measurements and the conversions between them.
There are also tons of machines and tools made to work in inches. As more things are becoming computer controlled, it's easier to convert between inch and mm on the fly, but every drill bit, end mill, and tool holder for the manual mill in my company's shop is in inch.
I'm also gonna disagree with you on the 12 better than 10 front. Just use a calculator if you can't do it in your head and round to the nearest mm. I bet you'll learn what 10/6 and 10/3 are faster than 12/5 too.
I can actually do all of those in my head, so that wouldn't be an issue for me.
But yeah, all of my tools and bits and holders are imperial, and someone else better be paying to get the damn things replaced or they are staying imperial even if we go metric. I think the only things I have in metric are allans (allens? I've never had to spell it out), like 2 hole saws from an old project, and a set of calipers I was gifted and have used maybe twice
Everyone thinks the the switch would somehow be overnight and everyone would be required to throw away their old stuff. In reality, you just replace the things when they wear out and all the new equipment is metric. Tada!
