    Nah it’s more relatable to humans regarding electricity consumption, the consumer would be confused and scared seeing 3.6 megajoules on a bill and not actually understand how power usage of watts of appliances would convert into Joule energy units. That’s why electric cars motor powers are still rated in Watts and the bill shows a relatable term.

    To add to that, that’s why so many metric countries (not USA) still use imperial units colloquially because they are more relatable in real life like lbs and inches and feet. But then would use Km and grams in other contexts quite normally. And knots still always make more sense to pilots and sailors.

      People are just used to kWh. There’s nothing about it that’s more intuitive, it’s just more familiar. But measuring things in hogsheads and barleycorns used to be familiar too. Sometimes being familiar isn’t as important as following standards. Eventually the standard units will become familiar, and since they’re standard units, they’re much easier to work with.

      not actually understand how power usage of watts of appliances would convert into Joule energy units

      1 joule per watt each second. It’s dead easy. That’s why Joules should be used.

      That’s why electric cars motor powers are still rated in Watts

      Yes, power should be measured in Watts, that’s the standard unit for power, just like Joules are the standard unit for energy.

      To add to that, that’s why so many metric countries (not USA) still use imperial units colloquially because they are more relatable in real life like

      No they’re not, it’s just that people are used to them. The people whose minds are the hardest to change are the old people who have used some random unit for all their lives and don’t want to have to get used to some newfangled standard (a standard that’s actually hundreds of years old at this point). Because the old people refuse to change, the country gets stuck using that old unit, even if it’s informally, and so that’s what the kids learn, then they become old people and are also inflexible.

      There’s nothing about an inch or a pound that’s naturally more intuitive than a centimetre or a kilogram. It’s just what you’re used to. Go somewhere where people grew up with metric and for them using anything other than metric feels strange and awkward. Pilots and sailors are used to knots, they never had to switch, but when they do complex calculations they mostly avoid using knots because doing conversions with non-SI units is such a massive pain in the ass.

      Sorry you totally lost me on the second paragraph. What you describe there is basically a British thing. On the continent people use m, kg and such for daily life things.

      Knots are used because of historic influences and inertia. Imperial units in some special cases are exclusively used because of the influence of the US and again inertia.

        Oh ok just a British thing so the ENTIRE BRITISH EMPIRE. Cool. Oh knots are used for historic influences like… Places that use imperial units colloquially but are official metric? Ohhh cool as well. Thanks for repeating just what I said and agreeing.

          If you head actually read what I wrote instead of just making stuff up, you’d know that I was talking about the European contintent, on which, the tiny peninsula of Gibraltar aside, the British Empire had zero possessions after metrication. People there don’t use “inches” or “pounds” colloqually. Where I life they also don’t use some local old customary units for that, they simply use SI units for weight and dimensions. You are 176 cm tall and weigh 73kg …

          And that does contradict your claim that generally people prefer those old customary units in daily life. They only do if they were raised that way.

          The reason why customary units are still more widely used in daily life in regions formerly part of the British Empire is because there metrication was much more delayed, ie happened for real a lot later. The old ways take time to wither away, like they have in regions that had it all a lot earlier. It is ridiculous to suggest that those customary units are more useful to people in daily life but only if transition to metric for real wasn’t too long ago.
