The same formula can be used to determine the capacity of the house's overall electrical service. Because a home's main service is 240 volts, the math looks like this: 240 volts x 100 amps = 24,000 watts. 80 percent of 24,000 watts = 19,200 watts.

["The number of watts is equal to amps multiplied by volts. That's it! ... ", 'For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).', 'This is why watts are sometimes called volt-amps.']

Preliminary electric power load estimates can be made by using the approximate value of one kilovolt-ampere of input per horsepower (hp) at full load. Preliminary estimates of lighting loads may be made by assuming watts per ft2 of building area.

Divide this number by 1000 to find kilowatts. For example, an appliance that uses 12 amps and runs on North American electricity would use 1440 Watts, or 1.44 kilowatts.

You can estimate the total running load by adding up the running wattages of all items to be powered. If the name plate show only amps and voltage the wattage can estimated by multiplying volts times amps to calculate watts. Amps times Volts equals Watts. The watts total divided by 1000 is kW.

To determine the wattage, use a simple multiplication formula. The ampere (or amps) is the amount of electricity used. Voltage measures the force or pressure of the electricity. The number of watts is equal to amps multiplied by volts.

Calculate Watt-hours Per Day One kilowatt is equal to 1000 watts, so to calculate how many kWh a device uses, divide the watt-hours from the previous step by 1000.

Using Ohms law, you would multiply amperage times volts to get watts. For instance a 12 volt circuit drawing 2 amps would consume 24 watts of power (12*2=24). A 60 watt light bulb powered by 120 volts in a house would draw . 5 amp of current (60/120= .

So to find the current drawn, simply divide the power by the operating voltage. In the United States, most household appliances work at 110 Volts. So the calculation is divide the Wattage by 110. For example: A 40 Watts bulb draws 0.36 Amps to operate.

Multiply the width by the length for each room or room segment, if applicable. Multiply the result by 1.5 to determine the estimated watts to sufficiently light a room. For example, for a room 10 feet wide by 12 feet long, multiply 10 times 12 to get 120, then multiply by 1.5 to get 180 watts.

The best way to find out your PC's power usage is by measuring directly from the wall with a power meter like the Kill-A-Watt P3 P4400. Simply plug the meter into the wall outlet, and your machine into the meter, and the P3 P4400 will provide an accurate reading of your machine's power draw.

Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.
