Kva To Kw Formula
The following formula is used to calculate the power in Kilowatts (KW) from the power in Kilovolt-amps (KVA).
KW = KVA * PF
Variables:
- KW is the power in Kilowatts
- KVA is the power in Kilovolt-amps
- PF is the power factor
To calculate the power in Kilowatts, multiply the power in Kilovolt-amps by the power factor. The power factor is a unitless number between 0 and 1 that represents the fraction of the load power that is dissipated as real power.

What is a Kva To Kw?
KVA (Kilovolt-Ampere) and KW (Kilowatt) are both units of power. The main difference between the two is that KVA is a measure of apparent power, which includes both the real power (KW) and the reactive power (KVAR), while KW is a measure of real power, which is the actual power that can do work. The conversion from KVA to KW is typically done by multiplying the KVA by the power factor, which represents the proportion of the total power that is used to do useful work.
How to Calculate Kva To Kw?
The following steps outline how to calculate the Kva To Kw using the formula KW = KVA * PF.
- First, determine the power in Kilovolt-amps (KVA).
- Next, determine the power factor (PF).
- Next, gather the formula from above = KW = KVA * PF.
- Finally, calculate the power in Kilowatts (KW).
- After inserting the variables and calculating the result, check your answer with the calculator above.
