About Power Conversions
Power is the rate at which work is done or energy is transferred. It is a scalar quantity with magnitude but no direction.
The watt (W) is the SI unit of power, defined as one joule per second. Other common units include kilowatts (kW), megawatts (MW), and horsepower (hp).
Power conversion is essential in engineering, physics, and many practical applications. Different power units are often used in different contexts:
watts and kilowatts for electrical power, horsepower for engines and motors, and BTU per hour for heating and cooling systems.
Accurate power conversion is crucial for designing electrical systems, engines, and energy production facilities.

Power Units Explained
Watt (W)
The watt is the SI unit of power, defined as one joule per second. It is named after the Scottish engineer James Watt, who improved the steam engine.
Kilowatt (kW)
A kilowatt is a unit of power equal to 1,000 watts. It is commonly used to express the power output of engines and the power consumption of electrical devices.
Megawatt (MW)
A megawatt is a unit of power equal to 1,000,000 watts. It is commonly used to express the power output of power plants and large industrial facilities.
Horsepower (hp)
Horsepower is a unit of power equal to approximately 745.7 watts. It was originally defined as the power a horse could sustain while working. It is commonly used to express the power output of engines and motors.
Foot-Pound per Minute (ft⋅lb/min)
A foot-pound per minute is a unit of power equal to approximately 0.0226 watts. It represents the work done at the rate of one foot-pound per minute.
BTU per Hour (BTU/h)
A BTU per hour is a unit of power equal to approximately 0.293 watts. It is commonly used in heating, ventilation, and air conditioning (HVAC) applications.
