Clarify why you say the litre is not part of SI. Has it been replaced with the cubic decimeter because of the slight difference between the two (as detected by precise modern equipment), or is it because cubic decimeters and cubic meters meters make the liter (litre) unneeded? Likewise why is the hectare not to be used. Are we supposed to say 10,000 square meters or 100 ares instead of hectare?
