Square and cubic units are not making my life easier. Quite the opposite.

For example, when you jump from square kilometers to square megameters, the surface area just explodes even though there’s plenty of interesting and useful stuff going on in between the two. You would end up having a stupid number of digits which totally defeats the purpose of having prefixes in the first place. Same applies to cubic units, but the problems are just even bigger.

That’s why I prefer to use ml, l, kl, Ml, Gl, Tl etc. for volumes. We could do the same with surface area too. Maybe dig up the archaic are unit and start using sensible prefixes to make calculations easier.
