A kilowatt-hour is a unit of energy. The amp is a unit of electric current. Current and Energy are fundamentally different things, and cannot be compared directly. To determine the energy dissipated by a current one would need to know the time for which it flowed, and the potential difference through which the associated charge was moved. the product of current by potential difference by time would give the energy. If one assumes the current flows for one second through a potential difference of one volt then the energy in joules would be numerically equal to the current in amps. One kilowatt-hour (kWh) is 3,600,000 joules, so to get the answer in kWh divide the energy, expressed in units of joules, by 3600000 .
Or you can use an easier method, its called Ohms law however one element is missing, the voltage is required. according to Ohms law Watts= Volts x Amps so if the circuit is 120 Volts the answer would be found by 1000 watts (1kW) divided by 120 volts and you get 8.333 Amps forget the Joules unless your a master electrician and fully understand it, even though we use Ohms law because it is sooooo much easier. if you Google the Ohms law chart remember Power is represented by a P Current is Amps and will be represented by C or R, Resistance is Ohms and is represented by a R and Voltage is represented by E

∙ 15y agoThe amount of watts (or thousands of watts, Kw) is a function of current (amps) and voltage. There are no watts in an amp, they are totally different units of measure.
P = I * V
Where P is for watts, I is for current (amps), and V is for volts. If you have one thousand watts (1Kw) and one amp, then there are one thousand volts (1Kv). In a North American household, where the voltage is set at 120v, then something drawing two amps at 120 volts is considered to be 240 watts (2A * 120V = 240W).

∙ 14y agoThis is a complex question that requires you to do some reading, as it confuses even electricians. The applicable reference is: NEC 220.40 Feeder and Service Calculations Typically if you are asking this question you should call an electrician to help you. However if you read the applicable NEC article you will be able to calculate your own service.
If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely. When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off (multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., not a non-contact tester, which is non-definitive. This can be done by using a clampmeter, this is a instrument that clamps over the main incoming cable ( hot wire ) where it enters the distribution board. you set the meter to read amps and this gives you the total amps being used at that time.

∙ 12y ago1000 watts = 1 kw Watts = Volts x Amps x Power Factor Power Factor = 1 for resistive loads like a incandescent light bulb or a toaster. It decreases toward zero with loads like motors. You could pick .75 for a motor or something with a motor like the compressor in a refrigerator. So to find amps, given watts for a resistive load, just plug in the voltage. If 120 volts is assumed for a USA residential application Amps = 1000 watts / 120 volts
AnswerA watt is used to measure power. An ampere is used to measure current. Power and current are two different quantities. There are, therefore, no amperes in a kilowatt. Your question is rather like asking how many inches there are in a pound.
I'm sorry but I must disagree. Watts and amps are different quantities but are related. WITHOUT AMPS THERE ARE NO WATTS.
The question didn't ask whether they were related. It asked how many amperes equals one kilowatt.

∙ 13y agoIt depends on the volts and power factor. Please restate the question.

∙ 14y agoIn order to convert kilowatts to amps, multiply kilowatts by 1000 and divide by volts:
amps = 1000 × kilowatts / volts

∙ 9y agoAn ampere is used to measure electric current, whereas a kilowatt hour is used to measure energy. These are two completely-different quantities, so you cannot convert one unit to the other.

How do you calculate DC kW to amps?
In a DC circuit Power (P) in watts is equal to Voltage (E) times Current (I). 1000 Watt = 1 kW P = EI thus I= P/E For kW then I = (P x 1000)/E Example with Power of 2 kW and Voltage of 250 V DC: I = (2000/250) = 8 Amp
How do you calculate load in KW?
You have to know 2 things in order to perform the calculation. You will need to know the power (KW) and either the amps or the voltage. If you know voltage you can determine amps and if you know amps you can determine voltage. However with solely the KW you do not have enough information to calculate either. Here is the formula: 1 Phase: KW = (E x I x pf)/ 1000 3 Phase: KW = (1.732 x E x I x pf)/1000 Where E is voltage, I is current, and pf is Power Factor
How do you calculate 10 mw windmill power to kw?
1 MW is 1000 kW therefore 10 MW is equal to 10,000 kW.
Single phase 220 volts 2.6 kW how many amps?
You cannot convert 2.6 kw to amps with that information only. In order to convert watts to amps, you also need to know either current or voltage. This is because watts is volts times amps, and volts is current times resistance
How many amps does 1 phase 220volt 7.5 HP draw?
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
How many kwa in kva?
There are 1,000 watts (W) in a kilowatt (kW) and 1,000 volt-amps (VA) in a kilovolt-ampere (kVA). Therefore, 1 kVA is equal to 1 kW.
How many amps in1 KW for a 240v sistem?
In a 240V system, 1 kW is equal to approximately 4.17 amps. This calculation is done by dividing the power in watts (1000 watts for 1 kW) by the voltage (240V) in the system.
How many watts is 1.4 kw?
There are zero amps in 14 kW. A voltage needs to be stated. I = W/E, Amps = Watts/Volts.
How many BTU per hour is equal to 1 kW?
1 kW is equal to 3412 BTU per hour.
How many KW per Hp?
1 hp is equal to 0.746 kW.
How many kw does it take to make 100 amps?
If the 100 amps is powered by 10 volts, you have 1 kw, or 1000 watts. watts = volts X current The 'k' simply means kilo, or thousand.
How many kw in 480v?
To calculate the kilowatts (kW) when given voltage (V) and current (I), you can use the formula: kW = V x I x √3 / 1000 For 480V, the calculation would be based on the current flowing through the circuit.
How many amps for a 13.8 kw cooker?
To calculate the amps for a 13.8 kW cooker, use the formula: Amps = Watts / Volts. Assuming a standard voltage of 240V, the calculation would be 13,800 Watts / 240 Volts = 57.5 Amps. Therefore, a 13.8 kW cooker would draw approximately 57.5 Amps of current.
1 kw equal to how many units?
1 kilowatt (kW) is equal to 1 kilowatt-hour (kWh) when used continuously for one hour. So, if you use a 1 kW appliance for one hour, it will consume 1 kWh of electricity.
How many watts in a Kva?
1 kVA is equal to 1,000 volt-amperes. The conversion between volt-amperes (VA) and watts (W) depends on the power factor of the load. For resistive loads and a power factor of 1 (unity), 1 kVA is equal to 1 kW (kilowatt). However, for loads with different power factors, the relationship between kVA and kW varies.
How many kW is a MW?
1 MW is equal to 1000 kW, since "kilo" means 1000 times the base unit.
What is the relationship between kw and current?
The formula you are looking for is Watts = Amps x Volts. killo = 1000 1 kw = 1000 watts.
