[begin_snowed_in_random_musings] Let's face it: expressing the capacity or SoC of a battery pack is awkward for the average person. "Gallons" is easy, and is clearly a measurement of capacity that's intuitive to understand. "Kilowatt-hours" is not only a mouthful, but it's non-intuitive in that a kilowatt is a measurement of power, but must be expressed in conjunction with time in order to express energy, hence kilowatt-hour. For many folks this is rather confusing, doesn't directly relate to the application in their mind("Wait, so if I get 3 miles perkilowatt-hour, does that mean only if I'm driving at 3mph??"), and leads to incorrect usage (i.e.- saying "85 kilowatt battery pack"). So is "Megajoule" any better? It's still a mouthful, but seemingly somewhat less so (no hyphen!). It is a pretty foreign unit to most folks... but then again so is kilowatt-hour. And that may be an advantage in that folks won't try to shoehorn it in to an existing usage pattern, as they might with kilowatts. Admittedly "300 megajoule battery pack" is not exactly snappy, but at least a bit better (3 syllables vs 5!). I also wonder if "M-joules" would catch on. There's also the chance that you'd end up with something like calories, where the vernacular "calories" when talking about food is actually a "kilocalorie" (or large calorie). I may just start referring to my battery as a "Three hundred megajoule pack" for fun to see what happens.
