A kilowatt is an unit of true power in an AC circuit -as measured by a wattmeter.
A kilovolt ampere is an unit of apparent power in an AC circuit, which is the product of the voltage across a load by the current through it.
The relationship between the two is: kilowatt = (kilovolt ampere) x (power factor of load)
25kv=?kwAnswerA volt ampere (V.A) is the unit of apparent power, and applies to AC circuits that contain resistance and reactance. Apparent power is the vector sum of true power and reactive power. A kilovolt ampere is 1000 V.A. The volt ampere is the product of supply voltage and load current.
A kilowatt hour is the amount of energy consumed, over a period of one hour, at the rate of one kilowatt. It's used by your electricity utility company for measuring the energy you consume, for the purpose of billing. It's SI equivalent is measured in joules.A kiloampere hour is a unit of charge. It's SI equivalent is measured in coulombs. Batteries are often rated in ampere hours.
The correct symbols for reactive kilovolt amperes and kilowatts are kvar and kW, respectively.The simple answer is that you cannot convert one to the other. A reactive volt ampere is a measure of reactive power, and a kilowatt is a measure of true power. While these are related, they are different quantities, so you cannotconvert one to the other, any more than you can convert a kilometre to a kilogram.
These are two different values. kWh is the amount of kW that are used in an hour. To convert kW to kva use the same formula but leave out the pf (power factor) component.AnswerFirst of all your should realise that power is measured in watts (or kilowatts), not in kilowatt hours! A kilowatt hour is an unit of measurement for energy, or work done, NOT power! So your question doesn't actually make any sense!Furthermore, a kilovolt ampere is the unit of measurement for apparent power, and it should be written as 'kV.A', not 'kva'.So you cannot convert energy in kilowatt hours to apparent power in kilovolt amperes, as we are talking about two completely different quantities! It's like asking "How do you convert miles into kilometres per hour?" That's what I mean by your question not making any sense!The first answer needs correction, as the kilowatt hour is not 'the amount of kilowatts used in one hour'. You do not 'use' kilowatts, as kilowatts is simply a rate. So the correct definition is that a kilowatt hour is the amount of energy used in one hour, at the rate of one kilowatt.
It depends on (1) its voltage rating, and (2) whether it is single phase or three phase. And the symbol for kilovolt ampere is kV.A -not 'kva'.
Kilowatt per ampere you meant?Power = potential difference x currentSo, p.d = P/Iand can have the unit kilowatt per ampereOn the other hand, the physical quantity with the unit kilowatt-ampere has no meaning.

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.
I think you mean 'kW' (kilowatt) and 'kV.A' (kilovolt ampere). If the power factor is unity (1), then the number of kilowatts will be exactly the same as the number of kilovolt amperes -regardless of the supply voltage.
The volt ampere (V.A) is the unit of measurement of apparent power.Apparent power is the vector sum of a circuit's true power and reactive power.A kV.A (not 'KVA') is the symbol for kilovolt ampere, whereas MV.A (not'MVA') is the symbol for megavolt ampere. So the latter is one-thousand times greater than the former!

Unfortunately, the question as phrased is meaningless. A watt or kilowatt is a measure of voltage times current - one kilovolt at one amp of current dissipates one kilowatt of energy, but the same kilovolt at one tenth of an amp of current only dissipates 100 watts. Here's the formula: Watts = Volts * Amps
A kilovolt (kV, not 'kv') is the SI unit for potential and potential difference (voltage), whereas the kilovolt ampere (kV.A, not'kva') is the unit for apparent power. These are quite different quantities, so you cannot change one to another -if that is what you are asking.
In case of unity Power factorOne Watt is = 1 Volt - Amp (from the formula P = I x E),One kilo Watt is a kilo Volt Amp.1 kW = 1 kVAFor PF = 0.8, 1 kVA = 0.8 kW
A miliamp is one one thousandth of an ampere. So, the difference is that a miliamp is much smaller than an ampere.
Kilo simply means 1000. Volt-ampere (VA) is a measure of power, similar to the watt. Volt is a measure of voltage, or electrical pressure. Voltage means electricity is available, but unless it is actually used, no current (amperes) flows, and no work (power) is done. Suppose you have a motor that needs 1000 volts to run, and when it is on it draws one ampere (amp) of current. We would say the motor supply voltage is one kilovolt. When the motor is running, we would say it uses one kilovolt-ampere (1KVA) of power (1 ampere * 1000 volts = 1000 VA or 1 KVA).
According to Wikipedia, all forms of power can be expressed in Watts, but typically one expresses only REAL Power in Watts (& Kilowatts).The standard is to express Apparent Power in Volt-Amperes (VA) (& KVA).The kilowatt is the unit of measure for true power; apparent power is measured in volt amperes.However, the volt ampere and the reactive volt ampere (for reactive power) are traditional units, used to help differentiate between apparent, true, and reactive power. SI recognises the watt as the unit for each.
