To convert amps (electrical current) to watts (electrical power) at a fixed voltage, you can use the equation: watts = amps × volts. Simply multiply your amps figure by the voltage. Example calculations. 15 amps × 120 volts = 1800 watts; 20 amps × 120 volts = 2400 watts; Amps to watts at 120V (AC)
- Watts to Amps
By working backwards, we get the equation: amps = watts ÷...

To convert amps to watts, we need to use the following formula for electrical power: P (W) = I (A) * V (V) In a simple equation, here’s the relation: Watts = Amps * Volts. To calculate watts, we need both the amperage and voltage (usually either 120V or 220V). LearnMetrics has prepared handy amps to watts calculator you can freely use.
Just enter the voltage and current values of your charger, then click the "Calculate" button to get the charger power results. Be sure to use the information on the body charger to fill in the voltage and current values: Look for the voltage mark (V) or voltage on the body charger.
Convert amps to watts with our electrical conversion calculator, plus learn the formulas for DC, and single-phase or three-phase AC circuits.
This calculator will help you in finding the value of the Power (in watts) of the circuit by using Voltage and Current value. The Calculator works on the Watt’s Law formula given below: Power (P) = Voltage (V) x Current (I)
In Simple Amps to Watt calculator, you can calculate any value of Power in Watts, Current in Amperes and Voltage in Volts by entering any two known values for P, V or I.
Use the wattage calculator below to calculate the power in watts given the voltage, current, or resistance. Wattage is a measure of electrical power in watts.
