Question doesn't make sense. But if you have something that use or generate 5W per square meter, then you get 1kW if you have 200 square meter.
A 3 heat switch enables two elements for example of 1kw, to give out 100% power, 50% power and finally 25%. That equates to two 1kw elements in parallel. (100%) One 1kw element on power only. (50%) And finally both 1kw elements in series. (25%)
1Kw=1000watt
1kw electric power
1kW = 1.341 hp
1kW is 1.341hp
Electric rating of 1Kw
The cost of electricity depends on the rate charged by your utility company, not the voltage. The amount of power consumed (in kilowatts) determines the cost, regardless of whether it's at 240V or 120V. The rate charged per kilowatt-hour will determine the cost.
1kW : 3,412.142 BTU/hr
1kW = 1000W 50kW = 50000W
A watt is the product of Amps times Volts. It has nothing to do with a time interval. That said if that wattage is left on for a period of time, say 1 hour then it can be expressed as watt-hours. Because consumption in an average home is larger that just watts it is expressed as (kilo = 1000) kilowatts The meter on your house totals the amount of kilowatts hours you use in a month and this is what you are billed for from your utility company.
1kW = 20,472.852 BTU/hr
