Watts
A watt (W) is the SI unit of power, representing one joule of energy transferred per second, used to rate electrical devices.
Kilowatts
A kilowatt (kW) equals 1,000 watts, commonly used to rate the power of appliances, engines, and electrical systems.
Horsepower
Horsepower (hp) is a unit of power originally defined to compare steam engine output to draft horses, still widely used to rate vehicle and machine power.
BTU per Hour
British Thermal Units per hour (BTU/h) measures the rate of heat transfer, commonly used to rate the heating or cooling capacity of HVAC systems, furnaces, and air conditioners.
Megawatts
A megawatt (MW) equals one million watts, typically used to measure the output of power plants and large industrial equipment.
Joules per Second
A joule per second is equivalent to one watt, representing the rate of energy transfer or work done, used in physics and engineering.
