Free Watts to Amps Calculator
Calculate watts and kilowatts from voltage and amperage using Ohm's Law (P = V × I). Enter the voltage and current (amps) to find the power in watts and kilowatts. Useful for sizing circuits, calculating electrical loads, and understanding power consumption.
Frequently asked questions
How do I convert amps to watts?
Watts = Volts × Amps. For example, a 15-amp circuit at 120 volts can handle up to 1,800 watts (15 × 120 = 1,800 W).
How many amps is 1000 watts at 120 volts?
Amps = Watts ÷ Volts = 1,000 ÷ 120 = 8.33 amps.
