Amps to kVA Calculator
Amps to kVA Formulas
Single phase amps to kVA:
S(kVA) = I(A) × V(V) / 1000
Three phase amps to kVA:
S(kVA) = √3 × I(A) × V(V) / 1000
Where:
- S(kVA) = Apparent power in kilovolt-amps
- I(A) = Current in amps
- V(V) = Voltage in volts
- √3 = 1.732 (square root of 3)
How to Convert Amps to kVA
To convert amps to kVA, follow these steps:
- Select the phase type (Single Phase or Three Phase)
- Enter the current in amps
- Enter the voltage in volts
- Enter the power factor (typically between 0 and 1)
- Click “Calculate” to get the apparent power in kVA
- Use “Reset” to clear all inputs and results
Understanding kVA
kVA (kilovolt-amps) is a unit of apparent power in an electrical circuit. It represents the total power in an AC circuit, combining both the real power (kW) and reactive power (kVAR).
