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 Amps to KVA Calculation:
Short Note:
For example, let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance.
V(V) = 1.2 A ÷ 20 Ω
V(V) = 24 V
Ac Three Phase Amps to KVA Calculation :
Calculation with Line to Line Voltage:
Short Note:
For example, let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance.
V(V) = 1.2 A ÷ 20 Ω
V(V) = 24 V
Calculation with Line to Neutral Voltage:
Short Note:
For example, let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance.
V(V) = 1.2 A ÷ 20 Ω
V(V) = 24 V
Where:
-
- P = Power in watts
- V = Voltage in volts
- I = Current in amperes
- S = Apparent Power in Kilo-volt-amps (Kva)
- Cosθ = Power factor in AC circuits
- VL-L = Line to Line Voltage in 3-Phase Circuits
- VL-N = Line to Neutral Voltage in 3-Phase Circuits

Frequently asked questions
To calculate kVA from Amps, multiply the amperage by the voltage (v), then divide the result by 1000.
200 Amps at 12 Volts would be 2400 VA or 2.4 kVA.
The formula for converting kVA into kW is:
For example, a 200kVA generator with a power factor of 0.8 outputs 160kW actual power; 200 kVA x 0.8 = 160 kW.
How to Calculate Electrical Load Capacity for Safe Usage 20-amp 220-volt circuit: 20 amps x 220-volts = 4,400 watts.
A calculate the kVA rating for a single-phase transformer, you Will need to multiply the required input voltage (V) by the required current load in amperes and then divide that number by 1,000: V * l / 1,000.
