I used to live in France and I would sit in traffic in my car for 5km and nobody ever said "well at least the 5km is exactly divisible by 10 into 50,000 metres. It makes the traffic easier". Similarly, when the price of a 500ml glass of beer went up, nobody said, "well at least 500 is a factor of 1000, so it makes the beer taste better and it makes it cheaper, " and having 500g jars of jam instead of 484g (=1lb) jars of jam didn't change anything at all about the jam. Am I missing something? Is there some other part of everyday life that actually gets easier when you can divide it by 10 or by 100?

Now if we switched to metric time and had 100min hours, and maybe the same number of days in each month, that would genuinely make everyday life easier, right? But nobody seems promote that.
