# How Do You Calculate Watts?

To calculate watts, first get the voltage, current, and resistance for the device. Watts is the product of the volts and amperes of the device.
How to Calculate Watts
Whether it is for safety or economic reasons, knowing how to calculate watts can come in handy. Since electrical power (watts) is the result of electrical force (volts) pushing current (amps) trough a circuit, there are three different ways to calculate... More »
