Americans have long been the oddballs in the measurement world with our inability to accept the universal measurements like grams and meters, preferring instead our feet and inches and pounds. In fact, if someone tells me something in 3 centimeters, it won't mean much to me until they say it's just over an inch. You can tell me you ran 10 kilometers, but I won't really be impressed until I figure out that's just over 6 miles. We like our measuring units that we've grown to love even if we don't fully understand them (what's an acre, anyway?).
I'm rather fond of our measuring system, but I might be willing to add new units of measurement to that system, especially if they're anything like these that were posted on the Mental Floss blog. Now I can say, with pride, that I am roughly one smoot tall. That sounds so much cooler than 5'7".
