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.

A value of 30mA expressed in ampere would be?
A value of 30 mA (milliamperes) expressed in amperes would be 0.030 A (amperes). This is because 1 mA is equal to 0.001 A, so you can convert milliamperes to amperes by dividing by 1000. Therefore, 30 mA = 30 × 0.001 A = 0.030 A.
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 you convert 2.13mA to Amperes?
To convert 2.13 milliamperes (mA) to amperes, you divide by 1000 because 1 milliampere is equal to 0.001 amperes. Therefore, 2.13mA is equal to 0.00213 amperes.
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 the 1tr into kwh?
To convert 1 trillion watts (1 TW) to kilowatt-hours (kWh), you need to multiply by the number of hours in a unit of time. If you multiply 1 trillion watts by 1 hour (1 kWh = 1 kW * 1 hour), you get 1 trillion kilowatt-hours.
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 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 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 do you convert btu to ampere?
To convert BTUs (British Thermal Units) to amperes, you first need to convert BTUs to watts, using the conversion factor where 1 BTU/hour is approximately equal to 0.293071 watts. Then, you can use the formula ( I = \frac{P}{V} ) to find the current in amperes, where ( I ) is the current in amperes, ( P ) is the power in watts, and ( V ) is the voltage in volts. Simply divide the power in watts by the voltage to get the current in amperes.
What is 2A in mA?
2 amperes (A) is equal to 2000 milliamperes (mA), since 1 ampere is equivalent to 1000 milliamperes. To convert amperes to milliamperes, you multiply the number of amperes by 1000. Therefore, 2A x 1000 = 2000mA.
Formula for 7.5va convert into Amperes load comsumption?
To convert 7.5 VA to amperes, you can use the formula: Amperes = VA / Volts. For example, if the voltage is 120V (typical for household circuits), then 7.5 VA / 120V = 0.0625 amperes.
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
