What does 60w mean?

The rating 60 Watts means that the bulb will consume 60 Joules/sec and convert it into heat and light. Power = Voltage x Current. If the power supply is 120 Volt (It is usually 110–120 V in the US), then a current of 60/120 Ampere or 0.5 A will enter (and leave) the light bulb.

Can you convert kWh to kW?

How to convert energy in kilowatt-hour (kWh) to electric power in kilowatts (kW). You can calculate kilowatt from kilowatt-hour and hours, but you can’t convert kilowatt-hour to kilowatt, since kilowatt-hour and kilowatt units represent different quantities.
