In case of unity Power factor

- One Watt is = 1 Volt - Amp (from the formula P = I x E),
- One kilo Watt is a kilo Volt Amp.
- 1 kW = 1 kVA

For PF = 0.8, 1 kVA = 0.8 kW

0kva and kw are related as KVA = (KW/PF) pf:power factor

KVA·PF = KW 1.5 KVA x 0.8 PF = KW 1.2 KVA = KW 0.0012 KVA = W

120 KW @ 0.8 Power factor

Usually transformers are rated in kVA but if kW is specified, the kVA must be assumed to be the same. The kVA often exceed the kW but it cannot be assumed in this case.

If the power factor is 0.8 it's 150 kVA.

Kva = 0.9*kw

The answer: 17070 BTU The math: 3414 BTU = 1 KVA (KW) so 5 KVA = 17070 BTU

The same way, as you convert Appels to Carrots ........... There is a formula: KVAr = KVA / KW or cos=KW/KVA > Yes, we are treating KW, KVA, & KVAr as the 3 sides in a 90 deg TRIANGLE ! KW= vertical katede KVAr = horizontal katede KVA = hypotenuse

37.5 kVA

75 kva = kw

If the power factor is 1, i.e. a resistive load, the 1 KVA is 1 KW. If the power factor is less than 1, i.e. a reactive load, then multiply PF by KVA to get KW. For example, if PF is 0.92 and KVA is 1, then KW is 0.92.

7000 watts is 7 kW. To find the kVA, divide by the power factor, which is always 1 or less, so the kVA number is always either equal to or more than the kW.

KVA is the vector sum of real and reactive power; put differently, KVA at a specified power factor will tell you how many KW you have: KW = KVA * pf You must provide a power factor or power factor angle (if angle, replace pf with cos (pf) in above equation) or total reactive power to calculate.

KVA=KW*Power factor, considering PF 0.9, 6KVA=KW*0.9 KW=6/.9=6.67

KW is multiplication of KVA and power factor. Power factor is load dependent and varies as per the type of load. Hence the rating or capacity is mentioned in KVA not in KW

1 tone = 1540 Watts=1.540 KW. whereas 1 KW=1.25 KVA. I think you have got the answer.

200kw is equal to 250kva

KVAR is reactive power only; KVA is the vector sum of KVAR and KW KVA^2 = KVAR^2 + KW^2

we can calculate kwh,kva,kvah by following formulas kva=[(kw)2 + (kvah)2]1/2 kw=[(kvah)2- (kva)2]1/2 kvah=[(kva)2-(kw)2]1/2

For normal power factors (pf=80%), you have 0.8 kW for every kva. In general however, kW = pf x kVA. Where pf is the power factor, it is the cosine of the angular difference between the voltage and the current of a circuit in alternating current circuits.

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

KVA = KW + jKVAR KVA is full power, which includes the real power component (watts, or kW), and the reactive component (VARs, or kVAR).

kva*cos(phase angle)
