This resonated with me, because my grandfather had sheep. Sheep were weighed in kgs. People were weighed in stones. Feed in pounds. Sheep were sold in dozen and half-dozen dividable lots. Land in acres. In his region, one acre could feed one cow and one sheep so they had an intuitive serendipity. 100 acres made a viable farm.
Measurement systems tend to leave even more vestiges than other elements of language. Most of the world uses metrics, but almost no one advocates for metric time or angular units. Square kms never became an agricultural measure of land because one is bigger than most farms. Instead, metric hectares and metric dunams were adapted to be metric. They were close enough. Acres weren't, so there is no metric acre.
There are sixty minutes in an hour and 360 degrees in a circle because sumerians used a base 60 numerical system 5 thousand years ago. I have never even heard of a metric angular unit.
I totally accept the fact that metric systems are better. Engineering anything in inches seems impossible. OTOH, the richness and embedded history of language is valuable too. There's a reason esperanto never caught on, even though it's arguably the right tool for the job.
