Wattage = voltage times amperage. That's for DC. For AC there is a power factor PF = cos phi you have do multiply with.
Answer
The above answer suggests that power ('wattage') is an electrical unit, which it is not. In fact, power is defined as the rate of doing work, so the basic equation is work divided by time.

How do you determine system watts for lighting?
The equation is quite simple. Multiply the number of lights on the system by their wattage to determine the system wattage.
What will consume more wattage - a 110 volt appliance drawing 10 amps or a 220 volt appliance drawing 8 amps?
The equation for wattage is W = A x V. Substitute your values into this equation and you will have your answer.
How many watts does an electric piano use?
Look on the back of the equipment for a manufactures label. If the wattage is not on the label just use this equation Watts = Amps x Volts. This will give the wattage that the piano uses whenever it is turned on.
What is the current in the hair dryer if it is plugged into a 110- V outlet?
Without knowing the wattage that the hair dryer is rated at an amperage can not be stated. If you find the wattage, use this equation to find the amperage. I = W/E, Amps = Watts/Volts.
How much power is 1000000 volts?
1,000,000V is not a measure of power. You need the amperage in the equation to figure out the power (wattage). W = A x V
How many watts does a Mixie consume?
There are many models under the Mixie label. Look for the name plate and it will give you all of the information. If the wattage is not on the nameplate use the following equation to find wattage. W = A x V. Watts = Amps x Volts.
How many does volts and watts school smart vertical pencil sharpener use?
The volts will depend on what country you live in. The wattage can be calculated by the following equation. W = Amps x Volts. As you can see you need the value of the sharpener's amperage to obtain the wattage rating..
When computing wattage when to include power factor and square root of three?
In its simplest form the equation to calculate the wattage of an electrical appliance is: Watts = voltage x current. If the appliance is in a AC supply use the Route mean square voltage (the stated AC voltage).
How many volts are in sixty amps?
Amps are related to voltage in the following equation: Watts = Volts * Amps; so in order to answer your question, one would need to know the wattage.
How many watts does it take to run a 7.2 amp battery charger?
You need to mention the voltage to calculate the wattage
How may watt does a load of 3570 watt draw from an UPS of 2010 watt?
If the load wattage is 3570 watts then that is what the load wattage draws. Now by using the expression "draws" maybe you meant to say amps. If it is amperage that you are looking for then the answer can not be given without knowing what the voltage of the system the UPS is tied into.The equation to use is A = Watts/Volts.If a UPS nameplate output rating is 2010 watts then that is the maximum that the UPS is designed for by the manufacturer. Applying a greater load that what the UPS is rated for will void the warranty. Match the load wattage to the UPS's output when calculating what size is needed to operate correctly. This can be done by adding up all of the device wattages that will be connected to it. If the device does not have a wattage shown use the equation above to find the wattage.
Do the same wattage candelabra and incandescent bulbs draw the same power?
Yes, wattage is wattage, is wattage, is wattage. "Power" is calculated in wattage. It equals the voltage times the current in amps. In a light bulb, the resistive filament will cause a certain amount if current to flow making the filament hot and producing light.
