10 kva equals approximately 45.45 amps
Converting 10 kva to amps, assuming a power factor of 1, results in roughly 45.45 amps. This is because 1 kva is equal to 1,000 volt-amperes, and the calculation involves dividing the kva value by the voltage in volts if known, or using the formula for apparent power in AC circuits.
Conversion Explanation
The process of converting kva to amps involves understanding the relationship between apparent power, voltage, and current. When power factor is 1, amps are calculated by dividing kva by voltage (V). For example, if voltage is 220V, the amps are 10,000 VA / 220V = 45.45 amps. This formula helps determine the current based on the power in kva.

Conversion Formula
The formula used is amps = kva * 1000 / voltage. It works because kva (kilovolt-amperes) is a measure of apparent power, and dividing by voltage gives current in amperes. For example, with 10 kva and 230V, amps = (10 * 1000) / 230 ≈ 43.48 amps. This calculation assumes a power factor of 1, meaning real power equals apparent power.
Conversion Example
- Convert 15 kva at 240V:
- Multiply 15 by 1000: 15 * 1000 = 15000
- Divide by voltage: 15000 / 240 = 62.5 amps
- Result: 15 kva equals 62.5 amps at 240V
- Convert 20 kva at 120V:
- 20 * 1000 = 20000
- 20000 / 120 = 166.67 amps
- Result: 20 kva equals 166.67 amps at 120V
- Convert 8 kva at 230V:
- 8 * 1000 = 8000
- 8000 / 230 ≈ 34.78 amps
- Result: 8 kva equals approximately 34.78 amps at 230V

Conversion Definitions
kva
Kva (kilovolt-amperes) measures the apparent power in AC circuits, combining both real power and reactive power, and reflects the total capacity of electrical equipment to handle current at a specific voltage without considering power factor.
amps
Amps (amperes) are the units of electric current, indicating how many electrons flow through a conductor per second, and are calculated based on voltage and power in circuits assuming a certain power factor.
Conversion FAQs
How does the power factor affect the amps calculation from kva?
The power factor, a number between 0 and 1, indicates efficiency of power usage. When less than 1, the actual current (amps) is higher because real power is less than apparent power. Adjust the formula by dividing by the power factor to get true current.
What voltage should I assume if none is specified for converting kva to amps?
Typically, 230V is used as a standard residential voltage in many regions. If the voltage is unknown, specify your circuit voltage to get accurate current calculations or check local standards for your application.
Does this calculation change for three-phase systems?
Yes, in three-phase systems, the formula involves the square root of 3 (approximately 1.732). The amps are calculated using amps = (kva * 1000) / (voltage * √3), which accounts for the three-phase power distribution.
Can I convert kva to amps without knowing the voltage?
No, voltage is essential because the relationship between kva and amps depends directly on the voltage level. Without voltage, the conversion can’t be accurately performed.
