The International System of Units has a unit of electrical power called Watts.

Its unit is represented by the letter W, which means that a watt is the electrical power produced by 1V and 1A of current. We could represent it like this if we took into account the law.

I(A) x V(V) is 1A x 1V

The intensity or electric current can be obtained from the power in lines of DC or AC.

The current or intensity in Amps is the same as the power in Watts.

This can be seen in the formula.

P(W) / V(V) are the numbers.

If you don't know the value of the device's Resistive value, you may be able to figure it out.

If our electrical installation uses single-phase or single-phase alternating current, we can calculate the intensity of the phase by dividing the power P in Watts by the product that forms the power factor.

If the explanation is not very clear to you, this is the formula that summarizes the previous expression.

I(A) is the number P(W) and V(V) is the number PFC.

The power factor of a load is equal to 1.

We recommend that you use the exact one so that the calculations are accurate.

We have to differentiate between phase-phase and phase-neutral voltages in three-phase installations. Each case should have a formula that you should use.

If we have a three-phase installation and we want to calculate the Amp from the Watts knowing the phase-phase voltage, this is the formula to use.

I(A) is the number P(W) and the number VF-F(V) is the number PFC.

The formula is used to derive the intensity from the power in three-phase installations.

I(A) is the number of P(W) and VF-N(V).

We hope that you will be able to convert to watt in any of the possible variations.

We are going to do a generic example because knowing how many watt are 1 ampere will depend on many factors.

If you go to a campsite and they only offer 1 Amp, they are talking about direct current, which is what our electronic devices use.

We apply the first formula.

I(A) x V(V) is 1A x 220V.

It's a fair power but it may be worth it for some low-consumption lighting and appliances. In a campsite, you can get higher powers of up to 5 Amp.

Another example can be seen. Imagine if we had a transformer that converts the 220V alternating current to a direct current of 14.85V and 3.05A.

How much power is in the transformer? The formula from the previous example is applied.
