Is kVA equal to kW?
Answer : No, **kVA** (kilovolt-amperes) is **not** the same as **kW** (kilowatts). They both measure power, but in different ways. - **kVA** measures **apparent power**, which is the total power supplied by a source. It ... } \times 0.8 = 8 \, \text{kW} \] So, in this case, 10 kVA is equivalent to 8 kW....

How many kW is 10 kVA?
Answer : To convert from kVA (kilovolt-amperes) to kW (kilowatts), you need to know the power factor (pf) of the system. The formula is: \[ \text{kW} = \text{kVA} \times \text{Power Factor (pf)} \] ... on the power factor of the load. If you know the power factor, you can use it in the formula above....
