Amps to VA Calculator
Electrical Calculators
Convert between Amps, Volts, and Volt-Amperes (VA) for single and three-phase systems.
This calculator is based on industry-standard formulas and has been verified by our team of solar engineers.
Formulas:
Single Phase: VA = Amps × Volts
Three Phase: VA = √3 × Amps × Volts
Watts: Watts = VA × Power Factor
Common Power Factors:
- Resistive Load (heaters, incandescent lights): 1.0
- Motors (small): 0.8 - 0.9
- Computers and Electronics: 0.6 - 0.8
- Fluorescent Lighting: 0.5 - 0.9
- Induction Motors (loaded): 0.7 - 0.9
Key Points:
- VA (Volt-Amperes) represents apparent power
- Watts represent real power (actual work done)
- The ratio of Watts to VA is the power factor (PF = W/VA)
- For purely resistive loads, VA = Watts (PF = 1)
- For reactive loads, VA will be greater than Watts
When to Use This Calculator:
- Sizing UPS systems (typically rated in VA)
- Determining generator requirements
- Calculating power distribution needs
- Understanding power factor correction requirements
- Converting between different power measurements
