Watts to Amps Calculator: 3 & Single Phase Conversion

Watts to amps calculator for single phase and 3 phase electricity

This watts to amps calculator or reversal can helps engpocket friends to calculate both single phase and 3 phase just in seconds.

As a new engineer or for those who are not familiar in calculating and conversion, converting watts to amps, or reverse, is not very easy, we do not have time memories the formula, or sometimes in a hurry situation, we must get the answer quickly. That is why the watts to amps calculator above can help a lot.

Watts vs Amps? Voltage?

If you want to know more than just using the watts to amps calculator, here are explanations:

Watt

Watt (W) is the international standard unit for power or output. It measures the rate at which energy is used or produced.

Watt tells you how much work an electricity is doing.

Technically, one watt is defined as the rate of work done when one ampere of current flows through an electrical potential difference of 1 volt.

The basic formula is: Power (Watts) = Voltage (Volts) × Current (Amps)

Ampere

Ampere (A or I), can be shortened to amp, is the unit for electrical current.

It measures the volume or amount of electricity flowing through a circuit.

The basic formula is: I (Ampere) = V (Voltage) / R (resistance)

Voltage

Voltage (V or E), is the unit for electrical potential difference or electromotive force.

In simple terms, voltage is the pressure or the push that forces electricity to move through a wire. Without voltage, electrons would just sit still and do nothing.

The basic formula is:

Ohm’s Law: Voltage (V) = Current (I) × Resistance (R)

Power (Watts): Voltage (V) = Power (Watts) / Current (Amps)

Single phase VS 3 phase

Single phase is the standard usage for residential and small commercial applications. Three phase is often used in industrial and large manufacturing plants.

That is the end of our post today. Now, because we already know how to calculate watts, voltage & amps, you can also calculate breaker (MCB) size using our calculator in this link.

Have great day! See you on another post.
