"Watt" is a rate of using energy.
"4 kW" means 4,000 watts.
"4 kW for 6 hours" means 4,000 watts for 6 hours.
If you use energy at the rate of 4 kW for 6 hours, then altogether you use
24 kilowatt-hours, or 24,000 watt-hours, or 86,400,000 joules.

Is 1000 watt equal to 1 kilowatt?
Yes, but.... KWH = KW * H So any numbers that satisfy this equation are also one KWH. For instance: * 250 watts for 4 hours * 500 watts for 2 hours * 1000 watts for 1 hour * 2000 watts for 0.5 hours * 4000 watts for 15 minutes * etc. Keep in mind that kilo- means thousands, so KW means thousands of watts ( 1KW = 1000W).
How many watts in 4 megawatts?
4 megawatts = 4,000,000 (4 million) watts Mega means Million.
How many amp is 4 kw?
The amount of 4 kW is equal to zero amps. To find the amperage the following equation should be used. Amps = Watts/Volts. So you can see that it depends on the voltage of the circuit if the amperage is to be found.
How many watts would equal 75 kilowatts?
Power has 4 units to be precise. They are watts(W), kilowatts(KW), megawatts(MgW) and Horse power(HsP). 1kw=1000w 1mgw=1000000w ; 1HsP=746w; so 75kw will be 75000w.
What is the difference between using 100 watts for 2 hours or 50 watts for 4 hours?
In theory, no difference.
How many watts for 5kva?
Max 5 kW but it could be less for certain types of load, for example a motor. Most motors have a power factor of less than 1 . . . . 0.8 for example, which would give 4 kW from 5 kVA.
How much light does a1000 watt metal halide cover?
A 1000W metal halide lamp ballast uses about 8% of the lamp's wattage, meaning that a 1000W lamp actually consumes 1080 watts, or 1.08 kilowatts. STEP ONE - TAKE HOURS USED AND MULTIPLY BY 1.08 kW STEP TWO - TAKE THAT AND MULTIPLY IT BY COST OF ELECTRICITY, WHICH FOR RESIDENTIAL IN 2008 IS AROUND 11 CENTS/kWH (10 CENTS COMMERCIAL RATES)
How many Kw are 1 Hp air conditioner unit?
About 3/4 kW
How many watts does a 12 volt low voltage landscape light use in 4 hours?
The 12 v light should have the voltage and the power in watts printed on it. When it is running, it uses that amount of watts continuously. The energy is measured by the watt-hours, in other words the watts multiplied by the number of hours it runs for. 1000 watt hours makes 1 kilowatt-hour, which is a Unit on the electricity bill.
How many kilowatt-hours of electricity would be used by a 40-watt lamp that burned for 100 hours?
1 kW = 1000 w So 40 W / 1000 W = 0.04 kW As soon at the light is turned on, the lamp starts to use energy at the rate of 40 W = 0.04 kW. If you leave it on for 100 hours it will have used up 0.04 x 100 = 4 kWh
How many kilowatt hours does 4 100 watt light bulb use in 24 hours?
Add up all the individual watts, convert everything to kilowatts, then multiply by the number of hours.
Watt-hour a light bulb consumes 3600 watt-hours per day How many watt-hours does it consume in 4 days and 6 hours?
-9900
