What is Power?

Power is the rate at which energy is used or produced. Common units include:

• Watts (W) – Standard unit of power in the SI system.
• Kilowatts (kW) – 1 kW = 1,000 Watts.
• Horsepower (hp) – Commonly used in engines and motors, 1 hp ≈ 745.7 W.
• BTU/hour – Energy transfer per hour, used in heating/cooling.
• Joules per second (J/s) – Same as Watts, 1 J/s = 1 W.

Why Use a Power Converter?

• Easily convert between different power units.
• Useful for engineers, electricians, and students.
• Check unit conversions for engines, appliances, and energy calculations.
• Save time and avoid manual calculation errors.
