>>11210205SI is for industrial practicality primarily, and used in science incidentally. That's why you have pants-on-head retarded units like candela as a base unit, which is based on human psychosensory perception.
>>11210227 gives a good perspective on historical roots.>>11210261it's like making "dozen" a fundamental unit. We already have a unit for counting; it's called 1. btw, the new definition of mol breaks the traditional interpretation of the number of atoms in 1g of C12, as in this is no longer true with the new units
IMHO, base units should describe length, mass, time, and charge (in all its varieties like electric and color charge. mass is a type of gravitational charge, but since it is also inertial mass, it probably should be given it's own unit). Candela, mol, and kelvin are fucking imbecilic units.
