IMO the number one biggest contributor to this problem is "watt hours", it a cursed unit, a name which sows confusion. Even if it were named nonsense like "floops", the world would become a better clearer place. It automatically sounds as if it involves watts, hours, or even watts per hour, but it's actually none of those things. It's just (joules * 3600), where that fixed multiplier comes from a quirk of history in how we subdivided our clocks. My advice? Whenever you see it, replace it with "jumbojoules", as in "I used 87 kilo-jumbojoules running that appliance this month."
