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.

Which physical quantity has killowatt-ampere?
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.
How many kVA equal kWh?
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
What is the difference between Watts and Kilowatt hours?
Watts is smaller than kilowatts. watts is unit of power and kilowatts hour is unit of energy. Electrical devices are specified in watts where as electrical bill is for kilowatt hr use.
What unit is household electricity measured in?
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
How do you write a sentence with kilowatt?
We pay for the electricity by the kilowatt hour. An energy-efficient lightbulb has a low kilowatt usage rating.
What is the difference between Kilovolt Ampere and Kilowatt?
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)
Which physical quantity has killowatt-ampere?
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.
How do i Convert 12.5kw to kva?
I believe a kilowatt and a kilovolt-amp are mathematically equivalent units, but they are used in different contexts. Watts are used when talking about average or instantaneous power or "true" power. Volt-amps are used when talking about Apparent power.
How do you convert power reading in kWh to kva?
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.
How much is a wind power generator?
The cost of installing a home wind power generator depends on the kilowatt it produces. A 1 kilowatt wind power generator usually costs $3000-$7000. A 7 kilowatt wind power generator costs $20,000-$40,000. The more kilowatt it produces, the more costly it is.
What is power demand?
kilowatt demand ?
Does electric utility meter read real power or apparent power?
Energy meters monitor the supply voltage and the in-phase component of the load current -in other words, they read true (real) power not apparent power which, when time is taken into account (i.e. by the rotation of the meter's disc), results in a measure of energy consumed.
What are kw?
kW is kilowatt - a unit of power. 1 kilowatt is equal to 1000 watts: 1kW = 1000W
What is the difference between kilowatt hours and kilowats?
Kilowatts are a measure of electrical power. Kilowatt hours are a measure of how much electrical power has been used.
How many kVA equal kWh?
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
How many units of electric in a kilowatt?
Units of electricity as given on power bills are usually measured in kiloWatt hours. (kW.h) This is a kiloWatt of energy delivered for a period of an hour. It is a unit of power, and a kiloWatt is a measure of energy.
How to convert kva-kwh?
To convert from KVA (kilovoltamperes) to KWH (kilowatthours) first convert to KW (kilowatts) by multiplying by power factor. Power factor is the cosine of the phase angle between voltage and current. Then multiply by the number of hours that you run the load.
