1 Kilowatt is the same as 1000 Watts. The answer depends on two (actually three) things. What is the supply voltage, is the power source single or 3-phase, and is the load reactive (like a motor) or resistive (like a heating element or incandescent lamp)? For single-phase power feeding a resistive load: Amps = Watts / Volts Example: 1KW 120V baseboard heater: 1000W / 120V = 8.3A If the load is reactive, then you must take power factor into consideration. VA (Volt-Amperes) = Watts / PF (power factor) Amps = VA / Volts Example: A 240V motor that draws 3KW and has a PF of 0.83: 3000W / 0.83PF = 3615VA 3615VA / 240V = 15.06A The formulae for 3-phase power is exactly the same except you must divide the answer by 1.73. For instance, our 240V motor, if it were 240V 3-phase (for the sake of discussion) would be: 15.06 / 1.73 = 8.71A As you can see, power factor makes a big difference. VA is called "apparent power" because it's what you appear to have if you take measurements with a voltmeter and ammeter and do the calculations. Watts is called "true power", this is what you, the typical residential customer, pay the utility company for. Oh yeah, sometimes you will see PF expressed as a percentage. In our above example with PF = 0.83, you might find either 0.83 OR83% on the motor nameplate. If you run across the percentage figure, mentally convert it to the decimal number before using it in the formula.

∙ 14y agoampere is current, watt is power. they aren't interchangeable
however,
1 watt = 1 volt x 1 ampere
1 kilowatt = 1000 x 1volt x 1ampere

1 kilowatt is equal to how many amperes?
Kilowatts means power P and amperes mean electrical current I. That does not go together. Power is not current. There is nothing equal. 1 kilowatt means 1000 watts. You can make a calculation if you know the voltage V. P = V times I I = P / V = 1000 watts / x volt
How do you Calculate Pumping Cost using Horse Power and also Amp's?
Horse-power: convert that to kilowatt. Multiply by the time in hours you have the pump on, to get kilowatt-hours. Multiply the result by the cost of each kilowatt-hour. (Look at a recent electricity bill - if it doesn't explicitly state the cost per kilowatt-hour, you can divide the total of the bill by the number of kilowatt-hours consumed.)Amperes: You would also need the voltage. If you multiply amperes by volts, you get the power in watts. Divide the result by thousand to get kilowatts. Then continue as above.CommentAs the horsepower quoted for a machine is always its output power, you will need to know the efficiency of the machine in order to determine the input power (in watts), before performing the above calculations. The input power is always higher than the output power. Efficiency varies according to (a) the power rating of the motor, and (2) the actual load it is supplying, and can be less than 80% for smaller motors.
How do you convert A to mA?
m means milli, or thousandths. Multiply the number of amperes by 1000.
How do you convart kva to mva?
Because you are not using correct symbols, it's difficult to know what you are asking. A lower-case 'm' means 'milli' (one-thousandth), whereas an upper-case 'M' means 'mega'. Furthermore, if you mean, 'volt amperes', then the symbol is 'V.A', not 'va'. It's important to use the correct symbols, so people know exactly what you mean. I suspect what you mean is how do you convert kV.A into MV.A? That is, how do you convert kilovolt amperes into megavolt amperes (rather than 'millivolt amperes'). In which case, there are 1000 kV.A in 1 MV.A.
How do i convert 208 amperes to 120 amperes?
You can not change amp's amps is the result of voltage and resistance. Current is represented by I, Voltage is represented by E and Resistance is represented by R in ohms law. I=E/R, R=E/I and E=IxR the I is never a variable
How do you convert kw to bhp?
1 Kilowatt = 1.341 horsepower
How do you convert kilowatt-hours to gigawatt-hours?
Divide the kWh by 1 million
Convert 750 kilo watt to kilo joule?
1 watt = 1 joule per second 1 kilowatt = 1 kilojoule per second 750 kilowatt = 750 kilojoule per second
What is conversion of 1 liter of bunker fuel to kilowatt?
You can't convert that. A certain amount of fuel has a certain amount of energy; kilowatt is a unit of power, not of energy.
How many seconds in 1 kilowatt?
Kilowatt has no reference to time. Kilowat hour has one hour.
How do you convert amperes into kwh?
50
How much energy will a 1000w stereo use in 1 minute?
energy = power x time.In this case, you can either: * Convert the time to seconds, then multiply. The answer will be in watt-seconds = joules. * Convert the time to hours, convert the watt to kilowatt, then multiply. The answer will be in kilowatt-hours.
How Kilowatt to amperes?
The symbol for 'kilowatt' is 'kW', not 'Kw'.The kilowatt is used to measure power, whereas the ampere is used to measure current. These are different quantities, so you cannot simply convert one to the other. It's a little like asking "How do you convert kilometres per hour into newtons per metre?"!However, if you know that the power-rating of a kettle is 3 kW, and the supply voltage is 230 V, then you can find out the resulting current by dividing the power by the voltage. In this example, the current would work out at 13 A.
What electrical units do you rate a wind turbine and a power station?
Watts kW = (1 kilowatt = 1000 Watts) MW = (1 megawatt = 1000 kilowatts) GW = (1 giagawatt = 1000 megawatts) Volts Amperes
How do you convert 2.13mA to Amperes?
Divide 2.13 by 1000.
What is the formula to convert hp or horsepower to kilowatts or kw?
1 Horsepower equals 746 watt, or 0.746 kilowatt. To convert horsepower to kilowatt, one has to multiply the amount of horsepower by 0.746. For example: 500 hp = (500*0.746) kW = 373 kW
How do you convert giga watts electric to kilo watt hours?
Gigawatts and kilowatts are units of power, and 1 gigawatt = 1 million kilowatts. Energy is measured in kilowatt-hours or gigawatt-hours, 1 gigawatt-hour = 1 million kilowatt-hours.
