What is an Electricity Unit Converter?

An Electricity Unit Converter allows you to easily convert between different electrical units, including voltage, current, resistance, power, and energy — along with their metric and binary prefixes.

Why Use This Tool?

Whether you're an engineer, student, technician, or DIY enthusiast, this tool helps you quickly switch between units for calculations, reports, or project work without memorizing complex conversions.

How It Works

Select the units you want to convert between, enter the value, and the tool will instantly show the correct result using accurate formulas.

Supported Units

• Voltage: Volt (V), millivolt (mV), kilovolt (kV)
• Current: Ampere (A), milliampere (mA), kiloampere (kA)
• Resistance: Ohm (Ω), milliohm (mΩ), kiloohm (kΩ), megaohm (MΩ)
• Power: Watt (W), milliwatt (mW), kilowatt (kW), megawatt (MW)
• Energy: Joule (J), kilojoule (kJ), watt-hour (Wh), kilowatt-hour (kWh), megawatt-hour (MWh)

Conversion Formulas

These are the standard relationships used:

    Voltage:
    1 kV = 1,000 V  
    1 V = 1,000 mV

    Current:
    1 kA = 1,000 A  
    1 A = 1,000 mA

    Resistance:
    1 MΩ = 1,000,000 Ω  
    1 kΩ = 1,000 Ω  
    1 Ω = 1,000 mΩ

    Power:
    1 MW = 1,000,000 W  
    1 kW = 1,000 W  
    1 W = 1,000 mW

    Energy:
    1 MWh = 1,000 kWh = 1,000,000 Wh  
    1 kWh = 1,000 Wh  
    1 Wh = 3,600 J  
    1 kJ = 1,000 J
        

How the Tool Calculates

All conversions are based on multiplying or dividing by powers of ten (e.g., kilo = 10³, mega = 10⁶) or energy equivalencies (e.g., 1 Wh = 3,600 J).

Who Can Use This Tool?

This tool is ideal for electricians, students, hobbyists, and professionals in the fields of power systems, electronics, and physics.
