To convert amps (amperes) to watts, you need to know the voltage at which the current is flowing, as the formula for power (in watts) is:
Conversion Formula
Power (Watts) = Voltage (Volts) x Current (Amperes)
So, if you have a current of 15 amps and you know the voltage, you can use this formula to calculate the power in watts.
Solved example
Q. If the voltage is 120 volts
Ans. Power (Watts) = 120 Volts x 15 Amperes = 1800 Watts
So, 15 amps at 120 volts is equal to 1800 watts of power
