I was wondering about that post, because kW/s is not a common physical unit. Looking at GURPS Steampunk, I see that it has kWs, which is not kilowatts divide by seconds, but kilowatts times seconds, or kilojoules; that is, not a measure of power, or of the rate at which power increases, but a measure of energy.

To convert 1,872,000,000 kWs to kWh, you DIVIDE by 3600, to get 520,000 kWh. You seem to have multiplied, which is dimensionally wrong, and you also seem to have interpreted the figure you got as power (which can't be right with those units) rather than energy.

PS. Thanks, M.A. Lloyd, for independently deriving the same result and thus confirming mine.
