Electrical Unit Converters
Quick, reliable bidirectional unit conversion utilities for wire gauge standards, power, current, and mechanical motor ratings.
AWG to mm² Converter (Wire Size)
Convert American Wire Gauge (AWG) to cross-sectional area in square millimeters (mm²) and conductor diameter.
mm² to AWG Converter (Metric to AWG)
Convert metric cross-sectional wire area in square millimeters (mm²) to the nearest standard American Wire Gauge (AWG).
Watts to Amps Converter (W to A)
Convert electrical power in Watts (W) to electric current in Amperes (A) for DC, 1-Phase AC, and 3-Phase AC.
Amps to Watts Converter (A to W)
Convert electric current in Amps (A) to power in Watts (W) and Kilowatts (kW).
Volts to Watts Converter (V to W)
Calculate power in Watts from voltage when either current (Amps) or resistance (Ohms) is known.
kW to HP Converter (Kilowatts to Horsepower)
Convert Kilowatts (kW) to Mechanical Horsepower (HP) and Metric Horsepower (PS).
HP to kW Converter (Horsepower to Kilowatts)
Convert Mechanical Horsepower (HP) and Metric Horsepower (PS) into electrical Kilowatts (kW).
Amp Hours to Watt Hours Converter (Ah to Wh)
Convert battery capacity from amp-hours to watt-hours at 12V, 24V or 48V. The key step when sizing solar, RV and off-grid battery banks.
Watt Hours to Amp Hours Converter (Wh to Ah)
Convert energy in watt-hours back to battery capacity in amp-hours for a 12V, 24V or 48V bank. Essential when a load is rated in Wh or kWh.
Watts to VA Converter (W to Volt-Amps)
Convert real power in watts to apparent power in VA using the load power factor. The correct way to size a UPS, generator or inverter.
VA to Watts Converter (Volt-Amps to W)
Convert a UPS, generator or transformer VA rating into the real watts it can deliver at your load's power factor.
