Power Converter
Convert between amps, watts, kilowatts, and kilowatt hours
Start with amps
Use this when you know the current draw and want the resulting watts, kilowatts, and kilowatt hours.
Start with watts
Use this when a device already states its wattage and you want to estimate the current draw and total kilowatt hour usage.
Power draw is calculated as amps x volts, current can be estimated as watts / volts, and energy use is calculated as kilowatts x hours.
