What does this tool do?

Power is the rate of energy use. Engines are rated in horsepower or kilowatts, air conditioners in BTU per hour or tons of refrigeration, and appliances in watts.

One mechanical horsepower is 745.7 W, while metric horsepower (PS) is 735.5 W — car brochures in Europe often use PS. One ton of refrigeration is 12,000 BTU/h, about 3.52 kW.

Why use it?

  • Both horsepower definitions.
  • HVAC units included.
  • Exact factors.
