> how does this translate into US units, are there such simple conversions? Not really. I have a couple of these types of conversions committed to memory (1 gal water = 7 pounds, etc.), but it's all pretty ad hoc. That said, I haven't found too much use for it. All that said, I very much appreciate the orthogonality and consistency of SI. In an ideal world, the US would be on it, or at least on something the same as the rest of the world. Aside from sheer habit, I think the most compelling argument for the reason we aren't is that the units we use are so heavily baked into physical objects.
