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 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.
