Amps to VA Conversion Formula & Calculation Guide
To convert amps to VA, you need voltage and phase type.
Formula
For single-phase:
For three-phase:
Where √3 is approximately 1.732.
Step-by-Step Example
Example: Convert 10 amps to VA using 230 volts (single-phase).
1. Step 1: Write the formula:
VA = Amps × Volts
2. Step 2: Insert values:
VA = 10 × 230
3. Step 3: Calculate:
VA = 2300 VA
Result: 10 amps equals 2300 VA (single-phase system).
Three-Phase Example
Example: Convert 10 amps to VA using 400 volts (three-phase).
1. Step 1: Use the formula:
VA = √3 × Amps × Volts
2. Step 2: Insert values:
VA = 1.732 × 10 × 400
3. Step 3: Calculate:
VA = 6928 VA (approx.)
Result: 10 amps equals approximately 6928 VA in a three-phase system.

FAQs About Amps to VA Calculator
An amps to VA calculator converts electrical current (amps) into apparent power (volt-amperes) using voltage and phase type.
VA measures apparent power, while watts measure real power. VA includes reactive power in AC systems.
No. You must know the voltage to calculate VA accurately.
Single-phase uses a simple formula. Three-phase includes a √3 multiplier, which increases the result.
Yes. It helps size generators, transformers, and UPS systems correctly.
Three-phase systems distribute power more efficiently, so the calculation includes a factor of √3.
Yes. It provides accurate results when you input correct voltage and phase values.
Yes. Use it for appliances, circuits, and small electrical systems.
