Power Converter
Loading tool...
Understanding power is essential whether you're comparing car engines, buying a new air conditioner, or calculating the energy usage of your home appliances. Because different industries use different units like Horsepower, Watts, and BTU/hr, it can be hard to grasp the true output of a machine. Our Power Converter is a precise utility designed to simplify these comparisons for you.
If you're looking at engine specs, you're likely thinking in Horsepower (HP). If you're checking a light bulb or a computer power supply, you'll see Watts (W). Meanwhile, heating and cooling systems often measure output in BTU per hour. Our tool bridges these worlds, allowing you to instantly see how 200 HP translates to Kilowatts, or how many Watts a 5000 BTU AC unit is actually using. We even support the distinction between mechanical and metric horsepower for professional accuracy.
We believe that powerful math should be easy to use. Our converter works instantly in your browser on any device. There's no learning curve and no fees—just accurate results exactly when you need them. Whether you're an engineer, a car enthusiast, or just a curious homeowner, our Power Converter gives you the data you need to make informed choices every day.

Power Calculation Tips
What is Horsepower?
Horsepower (HP) is a unit of measurement for power, or the rate at which work is done. 1 Mechanical Horsepower is roughly equal to 745.7 Watts.
Watts vs. BTU/hr
Watts are the standard for most electrical devices. BTU/hour is primarily used for heating and cooling systems. 1 Watt is approximately 3.41 BTU/hr.
