If I'm paying 20c per KWh with the above PS3, does that mean I'd be paying 5c (250W/1KWh) per hour? |
You can see it already from the units that that's true
(250 * watts * 20 * cents ) / (1000 * watts * hour ) = (5 * cents ) / hour
Treat units as another thing to be multiplied and cancelled, it works out cleanly.
