@Suiseiseki SI units are based off absurd unreproducible constants.
Go ahead and produce me a vacuum and measure how far light travels through it in 1/299792458th of a second.


The "base units" are also silly
Ah yes, the base unit "6.02214076×10^23", so glad that exists.
Why is "kilogram" a base unit and not gram?
The wording in the definition of a Second uses a non-SI unit that itself is derived from a Second, therefore a Second is defined as a function of a Second???
