    Y’know, I had a feeling I put the wrong unit and then was like “nah… Sounds right”, I should have went with my first instinct

      you can think of the units of measure as multiplying and dividing sort of like the numbers themselves.

      So if the nuclear battery continuously delivers 1 watt…

      In one hour it would have delivered 1 Wh or watt-hour, because 1W * 1h = 1Wh.

      And it works in reverse. If it takes 2 hours to deliver that 1 Wh? That’s 1Wh per 2 hours or 1Wh/2h=0.5W!
