A total of
20 watts is equal to 20/1000 = .020 kilowatts.
One watt is 0.001 kilowatt. 65 watts is 0.065 kilowatts. It does not matter what the voltage is - watts are watts.
To convert watts to amps, use the formula: Amps = Watts / Volts. In this case, 3000 watts divided by 240 volts equals 12.5 amps. Therefore, 3000 watts at 240 volts is equal to 12.5 amps.
A 5kw heater draws just that, 5kw or 5000 w. If you have that switched on high, well I do not know what your supplier charges per kw hour, I am glad its not me paying.
To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.

A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.

Power (Watts) = Current X VoltageSo 7 X 240 = 16801680w
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.
P = E^2 / R P = (240 x 240)/ 8 = 7200 watts If this is coninuously energized for 24 hours: 7.2 kw/hr x 24 = 172.8 kw/hrs
The formula you are looking for is Watts = Amps x Volts. Transposed, Amps = Watts/VoltsAmps=Watts/Volts= (12.5 x1000)/240= 12500/240= 52.08 amps.
Watts are a function of volts times amps. A power factor is involved in motor loads, but we will discount that for now. You could have 1.25 amps flowing in a high voltage line representing a very large number of watts due to the high voltage, but lets assume we are speaking of a two wire, (hot and neutral) (the grounding wire would not be included in the calculation since it will carry no current in this example) 120volt circuit feeding say a small kitchen mixer. 120 volts times 1.25 amps = 150 watts If this were a residential 240 circuit, (2 hot wires) the watts would be double, (1.25 times 240=300 watts
Electric furnaces are rated in Kilowatts. The following formula will let you figure it out. Watts = amps x volts. For eg. a 10 Kw furnace draws 10000 watts. amps = watts/volts. 10000/240 = 41.6 amps. If your furnace differs from this example, just plug in your wattage and you will have your answer.
