# About This Calculator
Power is power, but different industries speak different languages. Car enthusiasts talk in Horsepower (HP), HVAC technicians speak in BTUs, and electricians deal in Watts (W) or Kilowatts (kW).
This calculator translates between these worlds, helping you size generators, understand AC units, or just satisfy your curiosity about how many horses are in your toaster (spoiler: usually about 1 or 2).
Common Conversions
- 1 Horsepower (Mechanical) ≈ 746 Watts.
- 1 Ton of AC Cooling = 12,000 BTUs/hr ≈ 3,517 Watts.
- 1 Kilowatt (kW) = 1,000 Watts = 1.34 HP.
Frequently Asked Questions
How many watts in a horsepower?+
One mechanical horsepower (HP) is approximately equal to 745.7 watts. Electrical horsepower is exactly 746 watts.
What is a BTU?+
A British Thermal Unit (BTU) is the heat energy needed to raise 1 pound of water by 1°F. It's the standard unit for Air Conditioners and Heaters.
How many BTUs is 1 Ton of cooling?+
1 Ton of cooling capacity equals 12,000 BTUs per hour. This 'Ton' refers to the amount of heat needed to melt a ton of ice in 24 hours (an old ice-house measurement!).
Why do cars use Horsepower?+
James Watt invented the term to market his steam engines to farmers. He calculated that a pony could lift 220 lbs 100 feet in a minute, approximated it to a horse doing 33,000 ft-lbs/min, and the unit stuck.
