🛡️ Reliable & Accurate
Single Phase is for residential applications (120/240V). Three Phase is for industrial/commercial applications (208/480V). The calculator automatically applies the correct multiplier (√3 for three phase).
Power Factor represents efficiency in AC circuits. Use 1.0 for resistive loads (heaters, lights), and 0.8-0.9 for inductive loads (motors, transformers).
Yes! Use the “mAh to Wh” calculator to convert battery capacity, then use the “Watts to kWh” calculator with your device’s power consumption.
Select “DC” in the Power Phase option for direct current calculations, or “Single Phase” for alternating current.
While useful for calculations, always consult local electrical codes and a licensed professional for commercial designs.
