Power and Energy Rate Conversions

Power conversion is essential for electrical systems, mechanical equipment, and energy efficiency calculations. Our converter handles all common power units.

Power Fundamentals

Watt (W) is the SI unit for power (energy per time). Horsepower for engines, BTU/h for heating/cooling, kilowatts for electrical power.

Mechanical vs. Electrical

Mechanical horsepower = 746 W, metric horsepower = 735 W. Electrical power in watts, kilowatts for household use, megawatts for industrial.

Efficiency Calculations

Power conversion helps calculate efficiency: output power ÷ input power × 100%. Essential for comparing equipment and energy costs.

Electric Grid

Power plants generate megawatts or gigawatts. Transmission losses occur over distance. Smart grids optimize power distribution.

Common Applications

Electrical systems, automotive engines, HVAC systems, industrial machinery, renewable energy systems, and grid management.

Conversion Tips

1 HP ≈ 746 W ≈ 0.75 kW. Household appliances: 100-2000W. Car engines: 100-500+ HP. LED bulb: 5-15W replaces 40-100W incandescent.
