Watt to BTU/hrBTU/hr = W × 3.4121
BTU/hr to kcal/hkcal/h = BTU/hr × 0.252
Ton to BTU/hrBTU/hr = RT × 12,000

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

Unified conversion between Watts, Horsepower, and BTU. Perfect for HVAC and Automotive analysis.

Guidance

Tips & Best Practices

💡
Remember that there are different types of HP (Mechanical vs. Metric); we use the standard Mechanical ratio (745.7).
💡
A BTUs (British Thermal Unit) is energy; BTU/hr is the standard unit of power for heating.
💡
A standard hair dryer is usually 1,500 to 1,800 Watts.
💡
One ton of refrigeration is equal to 12,000 BTU/hr.
💡
Human resting power output is approximately 100 Watts.
