When the voltage is known, as in the case with electrical outlets, the power in watts can be interpolated as long as the current in amps is known. Watts is a more comprehensive unit for power. For example, one horsepower is the equivalent of roughly 746 watts so you can describe a 2 horsepower engine as having 1492 watts of power output. On the other hand, watts can be used to describe power in other types of energy. As amps is the unit of current flow, it is easy to conclude that it is exclusive to electricity. If you want to measure watts on a typical appliance but you do not have a wattmeter, you can just measure the current in amps then multiply it with either 110V or 220V, depending on the standard voltage in your part of the world.Īnother difference between these two units is where you can actually use them. There are wattmeters available in the market that simplify this process but still operates on the same exact principles. To measure watts, it’s a bit more complex as you need to measure volts as well as amps then multiply the two values to get watts. To measure watts, you need to connect an ammeter in series. Just fill in one of these units pairs in the calculator above.

It is easier and simpler though to measure amps as you only need to connect an ammeter in series to the circuit in order to measure the flow. Using this converter you can make any of these calculations: watts to ohms, watts to amps, watts to volts, volts to watts, volts to amps, volts to ohms, amps to volts, amps to watts, amps to ohms, ohms to volts, ohms to watts and ohms to amps. For example: a device that draws 2 amps from a 12 volts source is consuming 24 watts while a device that draws 2 amps from a 24 volts source is consuming 48 watts.īoth amps and watts can be measured by instruments. The current in amps and the voltage of the source multiplied is equal to the power draw in watts. The amount of power can still vary depending on the voltage. There is a big difference between the two though as watts is a comprehensive measurement of power while amps is just the quantity of current being drawn. Amps and Watts are two things that you commonly hear when it comes to how much power will be consumed by certain appliances and lighting fixtures.
