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.

Convert 5.0KW to KVA?
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
An electrical meter shows an average monthly reading as follows kva 415 units per month kwh 120 units per month can this be correct we are paying a huge amount for the kva usage?
The meter shows the load has a very poor Power Factor of about 30%. It appears this service has a very large capacity -- most of it not used. Taking one or more (like for X-Ray or similar machine) transformers out of service may help improve PF.
Convert 20 kva to kw?
Your question cannot be answered, unless the power factor of the load is specified. Since true power(measured in watts) is the product of apparent power(measured in volt amperes) and the power factor of the load.So, given your figure of an apparent power of 20 kV.A(not 'kva'*), the corresponding value of true power could (theoretically!) range from20 kW at a power factor of 1.0, to0 kW at a power factor of 0.(*The correct symbol for kilovolt ampere is 'kV.A', not 'kva', and the correct symbol for kilowatt is 'kW', not 'kw'.)
How much 100ah to kva?
Some more information is needed. 100% power factor for one hour and 220 volts = 22 kva. At 0.85 power factor = 22/0.85 = 25.88 kva
Why transformer are rated in kVA instead of KW?
Transformers are rated in VA or kVA. That is because the voltage is limited by the power loss in the magnetic core, and the current is limited by the power loss in the resistance of the windings. The rated voltage times the rated current gives the transformer's rating in kVA.
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.
How do we Calculate Kwh to Kvah?
To convert 'kwh' to 'kvah' you first need to measure the length of time. You will then convert this amount to hours by dividing by 3,600. You will then divide this amount by the length of time.
Is there a difference between kWh and KWH?
There is no difference in the meaning of kWh or KWH. Both forms of writing kWh mean "kilo watt hours," and the format acceptable to most in the technical community is "kWh."AnswerThe correct symbol for kilowatt hour is kW.h.
How do convert KVA to KW?
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
How do you calculate kva to ampere?
You cannot convert them. KVA is a measure of power, while amperes are a measure of current.
How do you convert 110volts to kVA?
You must know the current or resistance to convert voltage to power.
Convert kw single phase to 3 phase kva?
KVA is the unit for the apparent power i.e it's the vector sum of the true power in KW and the reactive power in reactive volt-amperage. So, to get the value of the KVA for the 30KW,just divide the active power(30kw) with the power factor of that load.
How do you convert kwh to amps?
There is no kva in volts, kva stands for kilo = 1000, volt = working voltage, amps = maximum amperage draw at that voltage. eg. 1000 VA =100v at 10 amps or 200v at 5 amps. If you had a transformer that had a primary voltage of 480 volts and you need a secondary voltage at 240, with a maximum load of 5 amps, the transformer rating should be 1.2kva or 1200VA. On the premise 480V primary, amperage will be 2.5 amps. Secondary 240V, amperage will be 5 amps. 480 x 2.5 = 1.2 KVA, 240 x 5 = 1.2 KVA. Transformer size is 1200 VA or !.2 KVA.
Convert 2KW to KVA in single phase?
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
How much is the 80 percent load in Amps of cummins 500 KVA disel sets?
You need to convert KVA to KW. In order to do this correctly you need to know your power factor.,
How can you convert the kva rating into kw rating?
kva*cos(phase angle)
How do you convert KVA into Horsepower?
You cannot directly convert kilovolt amperes (kV.A, not KVA) into horsepower, because they measure two different quantities.A kilovolt ampere is used to measure apparent power, whereas the horsepower is used to measure true power. Remember that the horsepower is an Imperial unit, equivalent to the watt in SI.However, if you know the power factor of the load, then you can determine the true power from the apparent power, then convert the number of watts into horsepower.true power = apparent power / power factor
