Tekla, are you referring to ski bindings?
I don't get why so many people like the metric system so much. Decimals are nice if you're multiplying by 10 a lot, but, say, for cooking, I like ounces and cups and pints a lot more -- everything is powers of two, much simpler. For temperatures, zero is really cold and 100 is really hot -- what could be simpler? As to distances, well, I have a foot. It's about a foot long. I don't have a meter. It's not often I have to convert between linear and volumetric measurements, but in the westward explansion of the United States the conversion between linear and area measurements was very useful. One square mile is split into an 8x8 grid of 10 acre plots. Or a 4x4 grid of 40 acre plots. 40 acres and a mule makes a nice family plot. Fly over the Midwest on a clear day, and the impact is unmistakable. As for speed -- well, km/h messes it up with the annoying factor of 3.6 compared to m/s anyway. Why not invent a system in which a day is 100,000 ticks or something?
I hate using the metric system. It's so inconventient. The speed of light is 299,792,458 m/s. Planck's constant is 6.62606896 x 10^-34 Joule-seconds. How ridiculous. Why not just make them both 1? Then I could say I'm about 6 nanoseconds tall, and the speed limit on the highway is 10^-7.
