So, they’re defined by universal constants but one step removed. The argument for universal constants is so pointless. The metric system is just as ugly if you use anything besides base 10, and its definition as by the universal constants is just as arbitrary. Yes metric tends to be better for many uses, but it’s just as arbitrary as any other system.
How do you define inch without metric units? How much is that?
Traditionally? An inch is three barley corns long.
Every country has a different definition of inch.
It was a beautiful chaos before metric!
How do you define a metric unit without other units… by using universal constants. All units are defined by the universal constants.
Factually incorrect. That is true of metric units but not imperial. The inch is officially defined in terms of metric units.

It’s the size of a thumb. The Dutch translation is “duim”. These smaller units use tangible things to measure. A foot and a thumb is always on you.
Its the size of Kings thumb, so I guess it suits for USA now, when they have one.
Measure your foot and divide it by 12.
