What is the difference between Watt and Horsepower?
Watt (W) is the SI unit of power, while Horsepower (hp) is an imperial unit. One mechanical horsepower is approximately equal to 745.7 watts.
How do I convert kW to hp?
To convert Kilowatts (kW) to Mechanical Horsepower (hp), multiply the kW value by approximately 1.341.
What is BTU/h?
BTU per hour (British Thermal Unit per hour) is a unit of power used mainly in heating and air conditioning industries. 1 W is approximately 3.412 BTU/h.
What is metric horsepower (ps)?
Metric horsepower (pferdestärke or ps) is slightly different from mechanical horsepower. 1 ps ≈ 735.5 Watts, whereas 1 mechanical hp ≈ 745.7 Watts.
Understanding Power Units
- Watt (W): The standard SI unit, defined as one joule per second.
- Kilowatt (kW): 1,000 Watts. Commonly used for residential electricity consumption and electric motor ratings.
- Megawatt (MW): 1,000,000 Watts. Used for power plants and large scale grid operations.
- Horsepower (hp): Imperial unit, originated by James Watt to compare steam engines to draft horses.
