Power & Energy Calculators
Calculate power consumption, energy costs, and efficiency conversions instantly. Optimize energy usage for industrial and residential systems with our accurate kilowatt, horsepower, and power factor calculators.
Power Factor Calculator
Calculate the Power Factor (PF) ratio from Real Power (kW) and Apparent Power (kVA). Improve system efficiency by identifying reactive power losses.
Energy Cost Calculator
Estimate the cost to run an electrical device over time based on wattage and local utility rates. Perfect for household budgeting and energy efficiency analysis.
mAh to Wh Converter
Convert battery capacity from milliamp-hours (mAh) to watt-hours (Wh). Essential for comparing battery energy across different voltage platforms like laptops and drones.
Wh to mAh Converter
Convert energy from watt-hours (Wh) to charge capacity in milliamp-hours (mAh). Useful for understanding power bank capacity relative to your device's voltage.
Joules to Watts
Calculate average power in Watts based on total energy in Joules consumed over time. Fundamental for physics problems and impact energy analysis.
Amps to kW
Convert current in Amps to electrical power in Kilowatts (kW). Supports both single-phase and three-phase calculations for generator and motor sizing.
