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 Kw to Kva Calculation:
The apparent power (S) in kilovolt-amps (kVA) is equal to the Real Power (P) in kilowatts (kW), divided by the power factor (PF):
For example, let’s find the apparent power in kVA for a 20 kW electric motor with a power factor of 0.8
S(KVA) = 20 / 0.8
S(KVA) = 25 KVA
Where:
-
- P = Power in kilo watts
- S = Apparent Power in KVA
- Cosθ = Power factor in AC circuits

Frequently asked questions
The kilovolt-ampere (kVA) is the power rating of a circuit conveying 1,000V and an ampere or 1,000A and a volt. A single kilovolt-ampere is comparable to a kilowatt.
As far as I know for a 2-ton inverter AC a 3.5 to 4 KVA stabilizer of 2533 watts is perfect. Let me tell you about four of the best AC stabilizers that you can buy for your AC.
kW is the unit of real power and kVA is a unit of apparent power (or real power plus re-active power).
KW is the abbreviation of kilowatt. In other words, it represents 1000W. It is the measure of Real power that is often converted into the form of usable output.
So a 3.5 kW appliance means an appliance that consumes 2.5kW of energy if it runs for 1 hour.
