Amps to kVA Calculator

Easily convert amps to kVA using our free online calculator. Supports single-phase and three-phase circuits. Fast, accurate, and ideal for electrical calculations.

Quick Intro: Convert Amps to KVA

To convert amps to kVA, multiply the voltage by the current and divide by 1,000. For three-phase circuits, include a √3 multiplier. This amps to kVA calculator works for both single-phase and three-phase systems, making it ideal for power load planning, transformer sizing, and electrical system design.

Formula for KVA Calculation

  • Single-Phase: kVA = (Volts × Amps) / 1000
  • Three-Phase: kVA = (√3 × Volts × Amps) / 1000

Amps to KVA Calculator Overview

The Amps to kVA Calculator helps convert electrical current in amperes (A) into apparent power in kilovolt-amperes (kVA). This tool is useful for engineers, electricians, and students working with AC circuits. The conversion depends on voltage, current, and whether the system is single-phase or three-phase. For single-phase: kVA = (Volts × Amps) / 1000. For three-phase: kVA = (√3 × Volts × Amps) / 1000. This calculator simplifies sizing transformers, generators, and power supplies by delivering quick and accurate results tailored to your input.

Frequently Asked Questions - Amps to kVA Calculator:

What is a kVA?

kVA stands for kilovolt-ampere, a unit of apparent power.

How do you convert amps to kVA?

Multiply amps × voltage × √3 (for 3-phase) or × voltage (for single-phase), then divide by 1000.

What’s the formula for single-phase?

kVA = (Amps × Volts) / 1000.

What’s the formula for three-phase?

kVA = (√3 × Amps × Volts) / 1000.

Why is √3 used in 3-phase calculations?

√3 accounts for the phase difference between voltages in a 3-phase system.

Can this calculator handle both phases?

Yes, it supports both single-phase and 3-phase conversions.

What units are required for input?

You need to input current (Amps) and voltage (Volts).

Is this calculator accurate?

Yes, it uses industry-standard electrical formulas.

What is apparent power?

Apparent power is the product of current and voltage without considering power factor.

Do I need power factor for kVA?

No, power factor is not used when calculating apparent power in kVA.
