Why don't we have one timezone covering the whole earth?
And instead changing the time work and other things happens depending on where you are. Would be easier to arrange meetings across the globe. Same thing applies to summertime. You may start work earlier if you want, but dont change the clocks!
One big argument I keep hearing is that it would be too expensive.
It's honestly not that bad. The estimated cost is around $350 million. Now, that might sound like a lot but when you take into account that it's about $1 per person it doesn't seem so bad.
Now, if you consider the military budget of $480 Billion per year it seems even smaller.
It would take approximately 0.07% of the 2024 military budget to switch to metric.
I imagine almost a bigger issue than the cost would be the... what's the American equivalent of a Gammon?... you know, those people that wouldn't change to Metric if their life depended on it. Four rods to the hogshead was good enough for their grandpappy and no filthy pinko liberal commie will get them to change. The ones that still don't wear seatbelts unless a cop is watching.
It's not cost, it's just apathy. For most people it would take a while to learn, especially since after school you're not really measuring that much in most jobs.
