Intro: Convert Amps to VA

Convert amps to volt-amperes (VA) quickly with this calculator. Just enter the electrical current and voltage to find out the apparent power in your AC system.

Formula & Table Summary

🔌 Single-Phase

Formula:

VA = Volts × Amps

Example: 230V × 10A = 2300 VA

⚡ 3-Phase (Line to Line Voltage)

Formula:

VA = √3 × Volts (L-L) × Amps

Example: √3 × 400V × 10A ≈ 6928 VA

⚡ 3-Phase (Line to Neutral Voltage)

Formula:

VA = 3 × Volts (L-N) × Amps

Example: 3 × 230V × 10A = 6900 VA

Frequently Asked Questions - Amps to VA Calculator:

VA stands for volt-ampere, a unit that measures apparent power in an electrical circuit. It’s the product of voltage (V) and current (A).

To convert amps to VA, multiply the current (in amps) by the voltage (in volts). The formula is: VA = Volts × Amps.

Not exactly. VA represents apparent power, while watts represent real power. In purely resistive loads, they can be equal (when power factor = 1).

VA accounts for both real and reactive power in AC systems. It's important for sizing transformers, UPS systems, and power supplies.

Apparent power is the combination of real power (watts) and reactive power (VAR). It’s measured in volt-amperes (VA).

No. Power factor is needed when converting VA to watts. But to get VA from amps, you only need current and voltage.

This calculator is mainly for AC circuits where apparent power is relevant. In DC circuits, watts = volts × amps, with no reactive power.

This calculator is designed for single-phase systems. For 3-phase systems, use the formula: VA = √3 × Volts × Amps.

Enter the voltage used by your equipment or supply source. Common values include 120V, 230V, or 240V depending on your region.

UPS systems are rated in VA. Knowing your total VA requirement helps ensure UPS can handle the full electrical load safely.
