Then why joules?

Watthours is another already fairly common unit.

1Wh lasts for one hour at one watt. Half and hour at two watts. And so on.

Amps are directly related. You can get the amps from the wattage, by dividing the watt with the voltage being run.

    Watthours are stupid. You're taking the SI unit of energy, the joule, dividing it by time to get watts, and then multiplying it by a different unit of time to get energy at a different conversion rate. It's ludicrous! I have a philosophical opposition to such confusing units.

    Or, think of it as just adding time to watts.

    If a thing uses 100 watts. Then in one hour, it used 100Wh.

    It's literally the simplest unit for this.
