This watts to amps calculator also known as amps to watts calculator or amperage calculator helps you understand how to calculate watts of a circuit depending on the type of the current.
Read on to find out how to convert watts to amps or vice versa and learn about the differences between line-to-line and line-to-neutral voltage configurations applied to three-phase currents. When talking about the fundamental Ohm's lawwe consider a few physical quantities: resistance Rvoltage Vand amperage I.
Electric current can also be a source of power P so that it can release or transport some energy. The SI unit of voltage is a volt, the unit of amperage is an ampere usually shortened to ampand the unit of power is a watt. All of these units from volts and amps to watts describe the voltage, amperage, and power respectively since they are shorter and easier to be pronounced. This convention is commonly used in the electronic world, so whenever you hear that somebody wants to convert amps to watts or watts to ampsyou will know that the person wants to find the relation between the amperage and electric power.
In fact, this question is not precise enough - you should ask: "How to convert volts and amps to watts? We can distinguish three main types of amperage:. The only thing we have to do is to choose the specific formulas which convert watts to amps for any type of flowing current. They are described in detail in the next section. The formula for DC watts to amps is a well-known expression for electrical power :. The expression used for AC single-phase current, which can be represented as a sine-wave signal, is very similar:.
It tells us about the ratio between the real power, which does the work, and the one supplied to the circuit. It varies from 0 to 1. The values close to unity is usually obtained for resistive-only loads, whereas the occurrence of capacities or especially inductanceslowers this value. Let's see how this amperage calculator works in practice.
Imagine that we want to know the power of a current with 15 amps and a three-phase alternating current, line-to-neutral voltage, with the amplitude of volts in other words, what is the result of conversion 15 amps to watts for VLN equal volts. We assume the power factor to be of the value 0. If you are uncertain about the result, just use our watts to amps calculator, pick the appropriate current type, insert all values, and check if there is any discrepancy.

If you are correct, there shouldn't be one! A three-phase current is usually applied in the electricity networks that are connected to our houses. Three-phase means that there are three distinct wires, each of which conducts the same signal but at a different phase. There is also another wire of neutral potential, referring to the ground.
The potential difference between any two cables is always higher than between any wire and neutral one. At the receiving end, all of these wires are joined together, and their configuration can be implemented in two ways, a star configuration or a delta configuration, which are shown in the following diagram:. The difference in the end connection results in different output power, which is the reason why you should choose the appropriate option of three-phase voltage in our watts to amps calculator.
By the way, you can always control the value of the voltage you want to deliver to your devices. If it turns out that the signal is too high, it's worth implementing some kind of voltage divider in order to reduce it.

Lorentz Force.Since amps and kilowatts are sued to measure the same quantity, it is possible to work out the amps given the volts and kilowatts. To calculate the current I in amps Ayou should multiply the real power Pin kilowatts by and divide the result by the voltage Vin volts V. Given that the power consumption by an electrical appliance is 0. Work out the phase current, in amperes, given that the power factor in a circuit is 0.
In this case, the phase current I in amperes Ais calculated by multiplying the real power Pin kilo-watts kW by and then dividing the result by the power factor multiplied by the square root of three times the line in line RMS V L- L voltage, in volts V. Given that the power factor is 0.

Multiply the corresponding voltage according to the formula by the power factor and by the root of three. For example, if I have a V fridge with a power factor of 0. Divide step 1 between step 2.
We have a monophasic sound equipment — alternating current AC of 1. A three-phase elevator AC consumes 9kW, has a line voltage of V and a power factor of 0. It has a bulb with a power of 0. Note: The conversions of the previous table were made taking into account a power factor of 0. For different variables you should use the calculator that appears at the beginning. Bhatia, B. The first thing you must do is enter the kW you want to convert, then choose the AC or DC current, it is important that once you choose the current you review the data shown on the left of the table, these change according to the current type chosen, then choose the number of phases: 1,2 or 3, this option will only be available if you choose AC current, continue entering the power factor, but if you know you can see the most common below.
Finally enter the voltage, it is very important that you observe the voltage that is requested on the left side of the table, because the correct type of voltage entered line-line voltage or line-neutral voltage depends on a good result, finally click on calculate to finish or restart to enter new values.

Home Electrical. Power Factor. Electronics device.Convert kilowatts kW to kilovolt-amps kVA by entering the power and power factor in the form below. Kilowatts kW measure the real power in an electrical circuit, while kilovolt-amps kVA measure the apparent power. In electrical equipment such as a generator or transformer the real power and apparent power are often not equal.
This is because the equipment has a power factor of less than 1, which represents the amount of power that does no real work in the circuit.

Line to line voltage Line to neutral voltage.Kilowatts and ampere are the units of two different parameters of electricity.
While the former quantifies the amount of power consumed by a load at any instant the latter quantifies the amount of current drawn by the load. You can use the following calculator to convert kilowatt to ampere kw to amps. Enter the kW, voltage, type of voltage and power factor for calculation. Since kilowatt kW is a measure of power and Ampere amp or A is the measure of current, kW cannot be directly converted into ampere or vice versa. Below are the formulae used to convert kilowatts to amperes kW to amps.
Therefore, amps can be calculated from DC — kW by dividing kilowatt by voltage and multiplying it by For a three-phase AC circuit, if the line to line voltage is knownampere can be calculated from kW using the following formula. For a three-phase AC circuit, if the phase voltage is knownampere can be calculated from kW using the following formula. Therefore, amps can be calculated from AC — kW by dividing kW by 3 times the product of the RMS value of applied phase voltage, power factor and multiplying it by You can replace it with the actual power factor.
