It's shorthand for a Joule (unit of energy) per second (unit of time). Watt is the problem with that?

  The real problem is the widespread usage of Wh as a unit of energy It would make way more sense to use J and J/h instead

    I regard that as a downstream effect of giving power a unit in the first place, but yes. We should have just stuck to J and J/s. It would have prevented the kWh and also abominations like the mAh “capacity” ratings you see on batteries.

    I gotta start describing distances as mph-hours

  Using watts is fine for anyone who deals with energy and power all the time. The problem comes when the lay person tries to reason about power. If power were written as J/s then they could use the same reasoning that they are already familiar with from dealing with speed and position, or with flow rate and volume.

  So joules per second per hour?
