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.
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.
Sample Amps to KVA Conversion Table
| Type | Amps (A) | Volts (V) | kVA |
|---|
| Single-Phase | 20 | 240 | 4.80 |
| Three-Phase | 30 | 415 | 21.56 |
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.
