So you are wanting to convert volts, amps, and watts. This is a rather simple conversion you can do with a calculator, you don’t need any special devices, but there are some devices out there that will convert volts, amps, and watts for you. Every electrical device in your home should have it’s voltage and amperage or voltage and watts printed on it. If not you will need to use a multimeter to find the voltage and amperage or voltage and watts.
But for those electrical devices in your home that have volts and amps or volts and watts printed you can convert amps to watts or convert watts to amps depending on what measurement you want.
If your electrical device in your home has the voltage and amperage printed on it you can convert this to watts by multiplying the voltage and amperage.
Voltage * Amperage = Wattage
So if you have a laptop that has 20 volt 4.5 amp printed on the power supply then that power supply is capable of using 90 watts.
20 volts * 4.5 amps = 90 watts
Pretty simple to convert volts and amps to watts. For those of your electrical devices that have voltage and wattage printed on the power supply, you can convert volts and watts to amps simply by dividing the wattage by the voltage.
Wattage / Voltage = Amperage
Now if your laptop’s power supply has 20 volt 90 watts printed on it, then you can take the watts and divide them by the voltage to get the amperage.
90 watts / 20 volts = 4.5 amps
Now if your electrical device does not show the voltage, amperage, or wattage you can use a multimeter to measure the voltage and amperage, then convert this to wattage.
