>Usually very physical based
Land records in the US are all feet, acres, furlongs, arpents, sections, and townships.
That's not changing.
And they all divide easily from townships of 36-square miles to 10-acre quarter-quarter-quarter-sections to 66x660ft-acres.
66 ft is a gunter's (surveyors) chain = 100 links
10 chains = 660ft = 1 furlong = 1/8 mile
It's a brilliantly thought out system, but most people promoting SI won't take the time to see the benefits.
Personally, I find it much easier to make blunders with SI, because a decimal shift one place over isn't always an obvious mistake.
