How do you calculate kw to kva?

Answer 1

A: They are both the same the first is the product volts times amperes the second is related to volts and amperes also. The difference is the second term is used to rate Transformers power output in terms of voltage to amperes. Example a 1kva means that you can expect 1kv at 1 ampere on the transformer output . But here is the trick the transformer only put out 250 volts So now what It means is 250v at 4 amperes nothing has changed the power remains the same 1 kw

<<>>

To convert KW to KVA just leave the power factor (pf) out of the equation.

Formula for Kilowatts = I x E x pf/1000.

Formula for KVA = I x E /100.

Answer 2

KVA = (Volts x Amps)/1000

Watts = (Volts x Amps x Power Factor)/1000

Power Factor is from 0 to 1 with 1 being related to a pure resistive load. Power factor is less than one for inductive devices like motors which are more likely to be rated in KVA or just VA. A KVA rating will therefore always be greater than or numerically equally to KW rating.

Another answer

You are mixing VA (Volt Amperes) and Watts. The "k" means 1000.

Watts = Volts x Amps x Power Factor

VA = Volts x Amps

Power Factor ranges from zero to one with one indicating a pure resistive load.

Therefore, 1 kVA = 1000 kW when PF = 1.

Answer 3

These units are used for completely different quantities, so you cannot simply 'convert' one to the other.

However, the volt ampere (unit for apparent power) is the product of voltage (unit for potential difference) and the ampere (unit for current).

Incidentally, the correct symbols are: 'kV.A' and 'kV'.

Answer 4

Watts = Amps x Volts x Power Factor.

VA = Amps x Volts

Watts and VA are equal only for resistive load where Power Factor = 1.

Answer 5

To convert from KVA (kilovoltamperes) to KW (kilowatts) simply multiply by power factor. Power factor is the cosine of the phase angle between voltage and current.

Answer 6

kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
