Look at your next utility bill. It will give you a price you pay per Kilo-Watt Hour or KwH. It will be cents. Like $0.11 per Kwh here in MI. Now that's how much you pay for every 1000 watts you use per hour basically. This means that you will pay that amount that is shown on your statement every 2.5 hours the device is in operation.
One horsepower is equal to 746 watts.
watts is a unit of power. joule is a unit of energy. The relationship between energy and power is: Power = Energy / Time. And 1 watt = 1 joule / second So you need to know how much time it took to deliver/transfer that 2400 joules of energy. If for example it took 1 sec, then you have 2400 w. If it took 1 minute (60 sec) Then Power = 2400 J / 60 sec = 40 w
A 3 watt LED has a power consumption of 3 watts. This means that it consumes 3 watts of electrical energy when operating.
1 kilowatt is equivalent to 1000 watts of energy, the average appliance will consume about 52 watts of energy. there for with the power of 200 kilowatts one would have enough power to reach mars in roughly 39 days
kWh and watts are two totally different units, so there is no way to convert one to the other. kWh, or kilowatt hours is a measure of energy, watts are a unit of power. You can convert watts to kW by dividing by 1000, so 1760 watts is equal to 1.76kW, but to get total power in kWh, you would need to then multiple your kW by the amount of hours in use.

Watts = Amps x Volts. This is the same as VA. So 2KVA is equal to 2000 watts.
The energy in a lightning bolt is estimated to be around 1 billion watts.

To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).
