Understanding Power Units

Horsepower (HP)

Primarily used in the automotive and mechanical engineering fields to measure the power of engines and motors.

Watts (W) / Kilowatts (kW)

The SI unit of power, universally used for electrical systems, appliances, and increasingly for Electric Vehicles (EVs).

BTU (British Thermal Units)

Commonly used in HVAC (Heating, Ventilation, and Air Conditioning) to measure the heat output of furnaces or the cooling capacity of ACs.

Refrigeration Ton (RT)

Used to describe the extraction of heat in large cooling systems like commercial chillers. 1 Ton = 12,000 BTU/h.

Therm & Quad

Units of heat energy used for large-scale energy consumption. Therms are common for natural gas billing, while Quads are used for national/global energy statistics.

Overview & Capabilities

The Power Engineering Studio is a multi-unit power converter for HVAC technicians, mechanical engineers, electricians, and facilities managers. Whether calculating residential air conditioner BTU cooling capacities (12,000 BTU/hr = 1 Ton of Refrigeration = 3.517 kW), sizing backup home generator kilowatt output from appliance electrical wattages, or translating mechanical horsepower, this studio converts seamlessly across imperial and metric power systems.
