One reason for having known standards is that you know what to expect.
Think of them like brand names, trust is important. If someone manufactures
a currency or coinage and then justs makes it whatever weight they feel like
whenever they feel like, it isn't going to be worth as much as if people
can depend on it to be right.

When you have to translate between many different units of length or weight
the chances of getting ripped off by the roundoff error increase. If you
don't believe me try exchanging your currency at an airport.
