6 kva equals approximately 27.27 amps when converting at a power factor of 1.0. This means a 6 kilovolt-ampere capacity can deliver about 27.27 amps of current under ideal conditions.
The conversion from kva to amps involves dividing the kva value by the voltage (in volts) and multiplying by 1000 to account for units, considering the power factor and system voltage. The formula generally used is: amps = (kva × 1000) / (voltage × power factor). For simplicity, assuming a standard voltage of 240V and a power factor of 1, the calculation becomes: 6 × 1000 / 240 = 25 amps. But if voltage is different, the amps will change accordingly.

Conversion Formula
The formula to convert kva to amps is: amps = (kva × 1000) / (voltage × power factor). This works because kva represents apparent power, which combines real power (watts) and reactive power. Dividing by voltage gives current in amperes, adjusted by power factor.
For example, if you have 6 kva at 240V and a power factor of 1, then amps = (6 × 1000) / (240 × 1) = 6000 / 240 = 25 amps. The division accounts for how much current is needed to support the given kva at the specified voltage and power factor.
Conversion Example
- Convert 10 kva at 120V, power factor 1:
- amps = (10 × 1000) / (120 × 1) = 10,000 / 120 = 83.33 amps.
- Convert 15 kva at 230V:
- amps = (15 × 1000) / (230 × 1) = 15,000 / 230 ≈ 65.22 amps.
- Convert 4 kva at 110V:
- amps = (4 × 1000) / (110 × 1) ≈ 36.36 amps.
- Convert 8 kva at 208V:
- amps = (8 × 1000) / (208 × 1) ≈ 38.46 amps.

Conversion Definitions
kva: Kilovolt-ampere (kva) is a unit of apparent power in electrical systems, combining real power and reactive power, used to size equipment and measure capacity in power systems.
amps: Amperes (amps) are units measuring the flow of electric current, indicating how many electrons pass a point in a circuit per second, essential for designing and analyzing electrical systems.
Conversion FAQs
Why does the amps value change with voltage when converting kva?
Because kva is a measure of apparent power which depends on voltage and current, increasing voltage reduces the current needed for the same kva, and vice versa, following the formula amps = (kva × 1000) / (voltage × power factor).
Can the conversion from kva to amps be accurate for all systems?
It is accurate when the power factor is known and assumed to be 1 or specified, and when voltage is constant. Variations in power factor or voltage lead to different amps values, so adjustments are necessary for precise calculations.
How does reactive power affect kva to amps conversion?
Reactive power, which does not perform work but sustains electromagnetic fields, influences kva because kva accounts for both real and reactive power. High reactive power increases kva without increasing actual work, affecting current calculations.
