| 16ths and even 32nds are common wrench increments. >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. |
