Watts = Amps x Voltage x Power Factor
Hence to compute watts you need to know voltage and power factor. If you have a pure resistive load like a light bulb power factor = 1 and can thus be ignored. If you are asking about residential power, the voltage is 120 VAC so the computation is now trivial.
What else can I help you with?
How many watts in one ampere?
One ampere is equal to one watt in a system with a voltage of one volt. This relationship is defined by Ohm's Law, which states that power (in watts) is equal to current (in amperes) multiplied by voltage (in volts).
How many watts of electrical power equal one horsepower?
One horsepower is approximately equal to 745.7 watts.
How many tera watts in one giga watt?
There are 1,000 terawatts in one gigawatt. This is because one terawatt is equal to one trillion watts, and one gigawatt is equal to one billion watts.
What is one quadrillion watts equal to?
One quadrillion watts is equal to one million gigawatts.
How many watts equals 1 ampere?
You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.
How many watts in one ampere?

How many microamperes are in an ampere?
One ampere is equal to 1000000 microamperes.
How many watts of electrical power equal one horsepower?
One horsepower is approximately equal to 745.7 watts.
How many watts in one MW?
1000MW is equal to 1GW
How many watts of power are equal to 1 horsepower?
The definition is that 746 watts equal one horse-power.
How much watts in one ampere?
Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts
A kilowatt-hour is equal to how many watts of electricity used for one hour?
1,000 watts
How many tera watts in one giga watt?
There are 1,000 terawatts in one gigawatt. This is because one terawatt is equal to one trillion watts, and one gigawatt is equal to one billion watts.
What is one quadrillion watts equal to?
One quadrillion watts is equal to one million gigawatts.
How do you convert volts to mva?
Do you mean 'megavolt ampere' (MV.A) or 'millivolt ampere' (mV.A)? By using the incorrect symbol ('mva'), this is not clear.To determine the apparent power, in volt amperes, you divide the true power, in watts, by the power factor of the load. One volt ampere is one-millionth of a megavolt ampere ('MV.A' -not 'mva') -assuming you don't mean 'millivolt ampere' ('mV.A')!

How many watts in a Kva?
A VA is a volt-ampere, or volt-amp, and a kilo (K) is one thousand. This makes a KVA a kilovolt-ampere, or kilovolt-amp. If we have 1,000 volt-amps, and one volt times one amp is equal to one watt (W), which it is, 1,000 volt-amps is equal to 1,000 watts, or 1 KW. All that said, 1 KVA is equal to 1 KW.Sometimes in an ac system, the watts is less than the volts times the amps, and in that case the watts is equal to the volts times the amps times the power factor. The power factor is less than one. The power factor for a typical electric motor is 0.7, so then there are only 700 watts in a kVA.
