9+ Easy Ways: How Do You Calculate Amps to Watts?

Determining power consumption from current draw requires understanding the relationship between amps, volts, and watts. The formula to convert amperage to wattage depends on the type of electrical circuit. For direct current (DC) circuits, wattage is simply the product of amps and volts (Watts = Amps x Volts). For example, if a 12-volt DC device draws 5 amps, its power consumption is 60 watts. However, alternating current (AC) circuits introduce a power factor, which accounts for the phase difference between voltage and current. Therefore, the formula for AC circuits is Watts = Amps x Volts x Power Factor.
