How to Use the Amps to kVA Calculator
Using our conversion calculator is simple:
Step-by-Step Guide:
- Enter phase number (1 for single-phase, 3 for three-phase)
- Enter the value of current in amperes
- Enter the voltage in volts
- Press the calculate button to get the result in kilovolts-amps (kVA)
The formula is:
kVA = (Amps × Voltage) ÷ 1000
This works for both line-to-line and line-to-neutral voltages, depending on the system.
Example: Three-Phase Amps to kVA Calculation
Formula:
kVA = (√3 × Amps × Voltage) ÷ 1000
| Current (Amps) | Voltage (Volts) | Power Factor | kVA Result |
|---|---|---|---|
| 50 A | 400 V | 1.0 | 34.64 kVA |
| 100 A | 415 V | 1.0 | 71.89 kVA |
| 150 A | 380 V | 1.0 | 98.82 kVA |
| 200 A | 400 V | 1.0 | 138.56 kVA |

Behind the Math: The Formula Explained
To convert amps, just multiply the amperage by the voltage, then divide the result by 1000.
For 3-phase:
kVA = (√3 × Voltage × Amps) ÷ 1000
For single-phase:
kVA = (Voltage × Amps) ÷ 1000
These power formulas are based on real-world use in electrical systems, helping you determine the apparent power in kilovolts-amps (kVA).

FAQs
How do I convert amps to kVA?
To convert amps to kVA, multiply the current (in amps) by the voltage (in volts) and divide the result by 1000.
Formula used:kVA = (Amps × Volts) ÷ 1000
Example: If you have 60 amps and 220 volts:
→ (60 × 220) ÷ 1000 = 13.2 kVA
How many amps is 1 kVA?
To convert 1 kVA to amps, multiply by 1000 and divide by the voltage.
Formula used:Amps = (kVA × 1000) ÷ Voltage
Example: For 1 kVA at 240V:
→ (1 × 1000) ÷ 240 = 4.16 amps
How many kVA is 200 amps?
Using a 3-phase supply at 400V, 200 amps is equal to around 138.56 kVA.
The formula used for 3-phase:kVA = (√3 × Volts × Current) ÷ 1000
→ √3 = 1.732
→ (1.732 × 400 × 200) ÷ 1000 = 138.56 kVA
Is 1 ampere equal to kV?
No, ampere (A) and kilovolt (kV) are two different electrical units. Amps measure current, while kV measures voltage.
Why:
They cannot be converted directly without knowing other values, such as power or resistance.
What is 1 amp equal to?
1 ampere is the flow of 1 coulomb of electric charge per second through a circuit.
Scientific Explanation:1 Amp = 1 Coulomb/second
This unit measures the amount of electric current flowing.
