The Watt’s Law formula is all that’s needed for this conversion. The wattage (power produced) is calculated by multiplying the amps (current) by the voltage... To convert amps (electrical current) to watts (electrical power) at a fixed voltage, you can use the equation: watts = amps × volts. Simply multiply your amps figure by the voltage.

Let’s say that we have a 5000 BTU portable air conditioner. This is considered a very small air conditioner; it’s powered by only 3 amps. How many watts does a 3 amp air conditioner use? It’s connected to 120V and we can use the upper amps to watts calculator to figure this out, like this: In short, 3 amps is 360 watts.
More powerful units, like washing machines and mini-split air conditioners, can be powered by 15 amps. How many watts is that? Here’s the calculation of 15 amps to watts at 120V: 15 amps are equal to 1800 watts at 120. If the voltage would be 220V, 15 amps would equal to 3300 W.
More powerful electrical units can draw as much as 100 amps. For these units, you already need amp breakers. 5 zone mini-split unitsare a good example of 100 amps electric devices. They are hooked up to 220V because 120V would need even more current. Here’s the conversion of 100 amps to watts: This is a massive 22,000 W device at 100 amps. If you h...
Calculation with line to line voltage. The power P in watts (W) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V): P(W) = √ 3 × PF × I(A) × VL-L (V)

For three-phase AC circuits where the current, line-to-line RMS voltage, and power factor are known, the formula to convert amps to watts is: P (W) = I (A) × V L-L (V) × PF × √3. The power P in watts is equal to the product of the current I in amps, the line-to-line voltage V in volts, the power factor PF, and the square root of 3.
