In general, multiply the (rms) current by the (rms) voltage to get the power.
If the voltage to the appliance is 120 Volts, then the power of 4.2 Amps is 504 Watts. If the voltage is 240 Volts, then 1008 Watts.
Note: To be technically accurate, you must also multiply the cosine of the phase-angle between current and voltage. For any typical appliance, this is 1 and can be ignored.

How many watts in 40 amps?
I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.
How many amps are in 200 watts 120 volt?
To find the number of amps in 200 watts at 120 volts, you can use the formula: Amps = Watts / Volts. Therefore, Amps = 200 watts / 120 volts, which equals approximately 1.67 amps.
How many amp is 115 volts?
To determine how many amps are in 115 volts, you need to know the power (in watts) being used. The relationship between volts, amps, and watts is given by the formula: Watts = Volts × Amps. Therefore, to find the amps, you can rearrange the formula: Amps = Watts / Volts. For example, if you have a device that uses 1150 watts, you would have 10 amps at 115 volts (1150 watts ÷ 115 volts = 10 amps).
How much power does a device that operates on 12 volts and draws 7 amps consume?
The device consumes 84 watts of power. This can be calculated by multiplying the voltage (12 volts) by the current (7 amps). So, 12 volts x 7 amps = 84 watts.
How many amps equal 3000 watts at 460 voltage?
To find the amperage, you can use the formula: Watts = Volts x Amps. Rearranging it, we get Amps = Watts / Volts. Plugging in the values for 3000 Watts and 460 Volts, we get: Amps = 3000 / 460 = 6.52 amps.
