minus-squareZink@programming.devlinkfedilinkEnglisharrow-up4·20 hours agoyou 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!
