kW, kWh and kilowatt/hour : What does it all mean?

A kilowatt/hour is a nonsensical unit in most contexts. If you find yourself using this unit, double-check what you really mean, which is probably kilowatt-hour. Kilowatt/hour means kilowatts per hour. Kilowatt is a measure of power (units: Joules per second ), so you are really saying joules per second per second, or joules per second squared.
