[sublinear]

This is rarely said, but often the key to undoing many arguments against the (what are now "US") units.

They come from a time where the common measurement tool was a balance scale for weight or two vessels of the same volume and any base unit was seemingly arbitrary. There was no understanding of universal constants yet. They're still useful when you have no reference other than the quantity indicated on the label of a package and the ability to measure equal parts.
