"I just don't see the value of metric for everyday purposes. For science, yes, but not for everyday measurement." Two systems of measurement for essentially the exact same things just complicates matters. Suggesting that your system is better (I'm (perhaps wrongly) assuming that it's because you learned one first) and more 'instinctive' or 'natural' is pretty poor argument. Are there any truly objective reasons you can argue one system (in your case, imperial/customary) is actually better? Yes, some units have slightly nicer divisible quantities, but that's easily outweighed by the crazy inconsistencies between different units of a type (stones, pounds and ounces, for example). Or inches, feet, yards & miles. There's no obvious relation whatsoever, and while there maybe be historical justifications for their values, they're not exactly arithmetically convenient. Or the horrible mess that happens when you get into fractional quantities. How much is 17/32" + 1/4"? Sure, I can work it out, but just adding some decimals together is a darn sight easier[1]. That can be done in either system, but imperial/customary definitely seems to favour it IME. Ultimately, I think people are going to have a preference for whichever they learn first, and intuitively approximate. For that reason, making a distinction between 'those fancy-pants science units' and 'good ol' everyday patriotic inches' strikes me as a foolish compromise that benefits neither. I could probably object to other things in your original post as well, but maybe I'm just projecting my childhood biases the other way. [1] for me, anyway. I've grown up with a bastard hybrid knowledge of mostly metric/SI, but enough exposure to imperial that I can intuit some, but not all of the conversions. Temperature is probably my weakest. I know from memory that 37oC ~98F, and that conversion is 5/8x + 32 or something along those lines. But to see '250F' and set my oven correctly, I have to think a bit. Or to guess if a temperature is below freezing or not. Having a hobbyist/armchair interest in machining & woodworking, the mental mode-switching when reading/watching videos by Americans vs everyone else is jarring.
