Ah! Right, yeah that unit is unfortunate. After moving into a place where electricity is metered for the first time (beyond student living places where you just pay a flat rate as part of the rent), I started looking into what devices use how much. The '-hour' unit is so confusing, also when converting ordinary Watts to whatever-hours, you need to use a conversion factor of 60×60=3600 to get anywhere. Not intuitive at all. Had we just used Joules (kJ and MJ mainly, where 1 Joule = using 1 Watt for 1 second), then by using a 1 kW device (e.g. microwave) for 100 seconds you can instantly tell that 100 kJ is the amount of energy used. On a yearly a bill of 9'000 MJ, you can instantly grasp the relative size of 100 kJ = 0.1 MJ, maybe you do this daily so 365×0.1 = 36.5 MJ. I am terrible at mental math but this much I can do. Alas. At least, that's how I think it all works, it's not like I ever got to practice this outside of Factorio (consumption/generation is all in Watts and storage in Joules).
