How many watts of what service? I hardly believe there is any law that forces home owners to waste a certain amount of power.
Also, in most of the world (the notable exception being the United States), areas are measured in square meters, not in square feet.
2000 watts RMS is equivalent to 2000 watts. RMS (Root Mean Square) is a method used to measure the power of an electrical signal.
To convert arms (root mean square current) to watts (power), you need to know the voltage in the circuit. The formula for this conversion is: Power (W) = Current (Arms) x Voltage. Multiply the root mean square current (Arms) by the voltage in the circuit to get the power in watts.
If you tell us the starting temperature and the finishing temperature and the specific heat of the material this 200 sq ft is made of then we'd have a chance of answering this one. But let's say that you're talking about a room (you didn't say you were but let's assume this), then a rule of thumb calculation, where the assumption is made that it takes 10 watts to heat a square foot of room, would show that you'd need 2,000 watts.
For lighting using CFL bulbs you can use 10 square feet per watt. The volt-amps is the volts times the amps, or the watts divided by the power factor. Most CFL bulbs are marked with the voltage and the current.
To convert watts to horsepower, you can divide the number of watts by 746 (since 1 horsepower is equal to 746 watts). For example, if you have 1000 watts, the conversion would be 1000 watts / 746 = approximately 1.34 horsepower.
To heat a room of 100 square feet, approximately 10,000 watts of power are required.
Watts, CA is 2.12 square miles.
For lighting use 0.1 watts of CFL per square foot, so 5-6 kW. In the summer, nothing for heating.
The conversion factor of 1 BTU = 0.293 watts. So, 60,000 * 0.293 watts = 17,580 watts. 17580 watts are required to run a craftsman 60,000 btu propane forced air heater.
2.4705 watts/hour
The area of Watts Bar Lake is 157.827 square kilometers.
The required power output for a well pump to operate efficiently is typically measured in watts.
2000 watts RMS is equivalent to 2000 watts. RMS (Root Mean Square) is a method used to measure the power of an electrical signal.
The average car requires about 400 to 600 watts of power to start.
To answer this question a voltage must be stated. W = A x V x pf.
4 watts 39.2 watts
None. Watts is unit of power. Square meter is unit of area.
