kWh is already an uncanceled unit, drives me nuts even without adding per day

(Energy / time) * time? fuck you

It's because the times aren't the same. Maybe same unit but different context so they can't be canceled.

It's like saying you work 8 Hours/day (Eight hours per day). Both are units of time, but their context is different and their combination forms a new meaning beyond the units.

1 KWh is using 1KW for one hour. Because of demand pricing the time you use that KW is important. Like in terms of energy grid using a whole ton of power for one minute vs same total over a long time is different and important dispite being the same amount of energy.

Edit: some phrasing

Gotta convert time to the same units before canceling: you work 1/3

Rough day today, I pulled 10 radians.
