Watts To KVA Calculator

Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.

Conversion Using the Power Formula :

AC Single Phase Watts to KVA Calculation:

The apparent power (S) in kilovolt-amps (kVA) is equal to the Real Power (P) in watts (W), divided by 1000 times the power factor Pf:

For example,  Let’s convert 8000 watts to kVA given a power factor of 0.90.

S(KVA) = P(w) ÷ 1000 x pf
S(KVA) = 8000 ÷ 1000 x 0.90
KVA = 7.200

Where:

    • S = Apparent Power in Kilo-volt-amps (Kva)
    • P = Real Power in Watts (W)
    • Cosθ = Power factor in AC circuits

Frequently asked questions

What Is kVA?

kVA Is short for kilovolt-amperes. It’s a unit of measurement used to refer to electricity in the form of “apparent power” in an AC (alternating current ) or DC (direct current) electrical circuit.
It’s measured as the product of the voltage, which represents electrical pressure, and the electrical current (amperes).
