4 amps how many watts

Since 1 kilowatt is equal to 1, watts, it is possible to use the formulas above to also convert amps to kW, but the result will need to be divided by 1, You can also use our amps to kW calculator to solve for kilowatts. You are here. Simple Advanced Current:. Voltage Type:. Power Factor:. I am trying to power a watt 2 channel audio amplifier 12 v rms per channel.

How many amps would I need the converter to put out? You would need your converter to put out 65 amps minimum. I have 4 ea.

Each of these units draws a bit less than 15 amps. For 15 amps, you can use gauge wires. Hope you find this useful. Hello Willy. Be aware that solar panels produce electricity at a lower voltage 12V or 24V. To get 16, Watts at 24V, you would need I want to purchase a heat press that has a v plug. It uses watts. Would a 30amp breaker be enough? Hello Darica, watts at V is a little below 30 amps. Hello Chris, kW is a huge wattage. You can use the electric power equation to easily see how many amps would be sufficient.

Hi … trying to learn about all this because my kitchen actually my whole house is electrically challenged. My fridge is I would think this would be too much to run both at the same time, but they have never thrown the circuit. Am I doing the math right? Hello Sandra, do both run on V? If they run on V, the amps are halved.

Additionally, the fridge might draw Most fridges run on much a lower percentage and hence draw much fewer amps.

I have an inverter AC watts, v. With the equation you provided, it consumes 7. Is this a feasible setup? Am I correct in saying I can run the AC even 24hrs? Hello Franz, two Ah batteries have a Ah capacity. However, the batteries run on 24V while AC runs on V. At V, it does consume 7. We live in our 5th wheel.

Generators run out of gas. I was thinking about deep cycle rv batteries and solar panels to charge the batteries during the day. There are many 12v deep cycle batteries that put out AH for their 20 hour capacity. Can 12V batteries provide that amount of power? I am considering hard wiring with switch boxes a amp welding mach.

Hello Roy, it depends on the voltage. Amperes A , volts V , and watts W are the 3 basic electrical units, connecting electrical current, voltage, and power. Every electric device — from air conditioners to washing machines and generators — includes them in their specification sheets. LearnMetrics has prepared handy amps to watts calculator you can freely use. Below the A to W calculator you will also find a table with calculated watts from amps for V and V voltage systems.

To illustrate how amps to watts calculation works, we have also solved 3 examples scroll down. For easier calculations, knowing how many amps are in a watt is very useful.
