Choosing the right power conversion
Power is the rate at which energy is transferred or used. Watts and kilowatts are SI units, while horsepower remains common for engines, motors, pumps, and some equipment specifications.
Power and energy are related but not interchangeable: a kilowatt is a rate, while a kilowatt-hour is an amount of energy accumulated over time.
Common uses
- Appliance and generator sizing
- Motor and engine comparisons
- Electrical project estimates
Power converters
Use converted values confidently
- One kilowatt equals exactly 1,000 watts.
- Confirm whether a source means mechanical, metric, or electrical horsepower.
- Do not compare kW directly with kWh.
