Watt-Hours are quite possibly the stupidest measurement of energy. „Oh let’s take a unit of joules per second and multiply it by a bunch of seconds. What do you think we get?“ Apparently not fucking joules.

And then applying SI prefixes to them? Absolutely perverse.

    How do people dare to measure the amount of work?

    Joules, as is the international Standard. 1 W•h = 3.6 kJ. One of the issues with watt-hours is that they’re so unconventional a unit that people think they’re a rate of change (Watts over time - W/h) which would be a measure of the fluctuation in wattage or colloquially an acceleration of energy. You so often see people doing crazy broken math with them as a result.

    Why use Joule, just use kg*m²/s².

    Square meter kilograms per second per second is even more intuitive.

    But more seriously, Wh and kWh is much more intuitive when determining energy consumption of your household. I don't want to calculate how many joules my fridge consumes per day!
