How many watts is being used by a motor pulling 13.1 amps at 220 v?

The formula you are looking for is Watts = Amps x Volts.
However, since the electricity is (probably) AC (wall power), you need to add an additional factor called "power-factor" because "AC" power doesn't work exactly like DC (battery) power.
So the formula becomes Watts = Amps x Volts x "power-factor" - where the power factor is a decimal fraction somewhere between zero and one. Note that power factor is never larger than 1.0.
Since the true power (multiplied by the power-factor) is always less than the "apparent power" (volts time amps without power-factor) you can use apparent power (also called "VA" - "Volt-Amperes" as a rough approximation.
Unfortunately - in the case of a motor, the power-factor is not constant. It varies rather widely based on both speed and load, so if you need to know the EXACT power, you need a direct-reading AC watt-meter.
If you want a closer approximation to "true power" - and you don't know the exact power factor - you can approximate it by multiplying "apparent power" by 0.71.

Is there a way for coverting amps into watts in a 12 volt applacation?
Watts = amps x volts. Something pulling 10 amps at 12 volts is 120 watts
What size is a motor that reads 4.8 amps on a juicer?
If it's 120 v 4.8 amps that is about 450 watts.
What are the running watts compared to the starting watts?
When you first turn on a motor it is starting from a static position and more current is required to get the motor up to speed (Starting current) than to keep it running (running current). Since watts equals amps times voltage you can see the difference in wattage is related to current. If you look at watts as work being done it is obvious that it requires more work to get the motor running than to keep it running.
What uses watts?
Watts are a measurement of electricity. Volts times Amps =watts So if you are using 12volt supply and pulling 3 amps you are expending 36Watts So anything that uses electricity is expending watts. Fridges, stereos, TV's, DVDs, computers, electric drills, etc
37.5 amps converted in watts?
To convert amps into watts a voltage is needed. Watts = Amps x Volts.

How many watts in a 115 volt refrigerator?
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.

If it's 120 v 4.8 amps that is about 450 watts.
How much each circuit breaker amperes do you need for 3 phase 2200 watts motor?
To answer this question the voltage of the motor must be given. Watts is the product of amps x volts. Amps = Watts/Volts. Once this is found the motor breaker needs to be larger to allow for the inrush start current.
How do you calculate hp from amps?
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
What is Full Load Amps?
FLA is the nameplate amperage rating of the motor when it is running at its designed horsepower and on the motors designed voltage. 746 watts = 1 HP. The FLA of a 1 HP motor at 240 volts would be W = amps x volts, Amps = Watts/Voltage. 746/240 = 3.1 amps full load. Overload the motor and the amps go higher, motor running at no load amps are lower than FLA

How many ampere in one hp?
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
The differene between amps and watts?
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.
37.5 amps converted in watts?
To convert amps into watts a voltage is needed. Watts = Amps x Volts.
What is stronger higher amps or watts in a electric motor?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. You can relate the two if you know the Voltage. For example, if your car has a 12V battery and your stereo draws 10 Amps of current, you are using 120 Watts of power. [Power in Watts] = [Voltage in Volts] x [Current in Amps]
