The SI units are not arbitrary quantities -- they are all physically derived quantities from water. For example, 1L of water weighs 1kg and and takes up 1000cc.

The SI units are not arbitrary quantities -- they are all physically derived quantities from water. For example, 1L of water weighs 1kg and and takes up 1000cc. Its density is 1000 kg/m^3. Simple. 235mL is just as easy to measure as 1 cup or 0.000992063492063492 Hogshead, you use your measuring cup. They are absolutely inherently better! They are an advantage in daily life. This is a very retrograde move. Imperial units are absurd and make calculations more difficult / less accurate. Edit: The Kg is arbitrary (you need a single arbitrary base), but everything else is derived from physical phenomena, including seconds: "The second is defined by taking the fixed numerical value of the cesium frequency ∆Cs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9,192,631,770 when expressed in the unit Hz, which is equal to s^–1."
