KW to Volts Calculator
Convert kilowatts (kW) to volts (V) using this calculator. Input power, current, and phase type (single or three-phase) to get accurate voltage in electrical circuits.
Quick Intro: Convert kW to Volts
The kW to Volts Calculator is a helpful tool for converting electrical power (in kilowatts) to voltage (in volts) based on current (amps) and system type (single-phase or three-phase). Voltage is a critical parameter in any electrical design, and knowing the right voltage helps in selecting proper wiring, devices, and protection systems. This calculator takes into account the power factor and phase configuration to give you the most accurate result. Whether you’re working on residential, commercial, or industrial projects, this tool simplifies the process and reduces manual calculation errors. Just enter the kW, current, and power factor, and choose your system type to get an instant voltage value.
Formula to Convert kW to Volts
DC Line voltage (V): V = (kW × 1000) ÷ I
Single-phase voltage (V): V = (kW × 1000) ÷ (I × PF)
Three-phase (Line-Line) voltage (V): V = (kW × 1000) ÷ (√3 × I × PF)
Three-phase (Line-Neutral) voltage (V):V = (kW × 1000) ÷ (3 × I × PF)
Where:
- kW = Power in kilowatts
- I = Current in amps (A)
- PF = Power Factor (typically 0.8 to 1)
- V = Voltage in volts (V)
kW to Volts Calculator Overview
Easily convert kilowatts (kW) to volts (V) using this quick calculator. Whether you're dealing with single-phase or three-phase systems, this tool helps you accurately find voltage based on power (kW) and current (A). The conversion varies by system type — for single-phase, the formula is V = (kW × 1000) ÷ A, and for three-phase, it's V = (kW × 1000) ÷ (√3 × A × PF), where PF stands for Power Factor. This tool supports residential, industrial, and engineering calculations. Just input your known values (kW and Amps), choose your system phase, and get the voltage instantly. It's ideal for electricians, engineers, students, and DIYers looking for accurate power-to-voltage transformations. Avoid manual errors and speed up your work with this simple yet powerful converter.

Frequently Asked Questions - KW to Volts Calculator:
How do I convert kW to volts?
Use the formula: V = (kW × 1000) ÷ (I × PF) for single-phase and V = (kW × 1000) ÷ (√3 × I × PF) for three-phase systems.
What inputs are needed for kW to volts conversion?
You need the power in kilowatts (kW), current in amps (A), power factor, and phase type (single or three-phase).
What is the typical power factor?
The power factor for most loads ranges from 0.8 to 1.0. Use 0.85 if you're unsure.
Can I convert kW to volts without amps?
No, you need the current (amps) to calculate voltage from kW.
Is this calculator suitable for 3-phase systems?
Yes, it supports both single-phase and three-phase voltage calculations.
Why is √3 used in three-phase calculation?
√3 accounts for the phase shift between currents in a three-phase system, ensuring accurate voltage conversion.
Is higher voltage better?
Higher voltage reduces current and losses but must match the equipment rating.
Can this tool help in motor sizing?
Yes, it's helpful in calculating supply voltage when motor power and current are known.
What if I enter the wrong power factor?
It will affect accuracy. Use real measurements or a typical value (like 0.9).
Does this calculate DC voltage?
No, this calculator is intended for AC systems (single-phase or three-phase).
