[–] RaccoonBall@lemmy.ca 2 points 8 months ago (2 children) Nitpick perhaps, but watts are not a unit of energy. permalink fedilink source parent hideshow 2 child comments replies: [–] gwl@lemmy.blahaj.zone 2 points 8 months ago* (1 child) 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 permalink fedilink source parent hideshow 1 child comment replies: [–] Zink@programming.dev 3 points 8 months ago 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! permalink fedilink source parent
